What Wins NFL Games? (or The Myth of Power Running)

What are the keys to winning football games? I have done a statistical analysis of the 2009 season to determine which metrics (yards, sacks, etc) have the most effect on winning percentage. The answers may surprise and dismay long-time Steelers fans. (For Johnny and other math guys, I applied a linear regression between each metric and the winning pct. for all 32 teams, then calculated the correlation coefficient R, which I have expressed as a percentage for simplicity.) I examined more than 50 different metrics and summarized the highlights.

Offense Metric Correlation to Wins
Points Scored 88%
Net Offensive Pts 90%
Yards Gained 77%
Yards per Pass Att 83%
Yards per Rush Att 0%
3rd Down % Made 64%
Red Zone Avg Pts 61%
Fumbles Lost 8%
Interceptions 64%
Sacks Allowed 44%

Let's start with a truism: the team that scores the most points wins. Scoring points has a 88% correlation with winning. Gaining yards is good, but only if it leads to scoring. I've also included net points for the offense, which subtracts return TDs; this metric is slightly better than points scored.

 

Now here's something interesting: running the football successfully has zero (0%) correlation to winning. None. Passing, on the other hand, has a very high correlation, particularly passing efficiency (yards per pass attempt). Not giving up sacks is important, as they reduce passing efficiency. Limiting interceptions is even more important. Fumbles appear to be random events that affect bad teams only slightly more than teams.

Star-divide

Defense Metric Correlation to Wins
Points Allowed 68%
Net Defensive Pts 75%
Yards Allowed 56%
Yards per Pass Att 60%
Yards per Rush Att 34%
3rd Down % 28%
Red Zone Avg Pts 36%
Defensive Hog Index* 48%
Fumble Recoveries 4%
Interceptions 41%
Sacks 41%

On defense, once again, points are more important than yards. (Net points again excludes return TDs and adds TDs that the defense scores.) The key thing here, however, is that keeping the other team from scoring is less important that scoring. In other words, a good offense is more valuable than a good defense. Stopping the pass is more important than stopping the run, but run defense is still useful. I've included CHFF's vaunted Defensive Hog Index here, but statistically, it has a modest correlation to winning, not much better than sacks or interceptions. Suprisingly, third-down defense and red-zone defense have a low correlation to winning.

Special Teams Metric Correlation to Wins
Kickoff Return Avg 5%
Punt Return Avg 1%
Net Kickoff Avg 15%
Net Punting Avg -27%
Net KR/PR TDs 3%
Field-Goal Percentage 3%

This data shows why most coaches pay little attention to special teams. Perhaps because special teams are not on the field very much, there is little correlation between special-teams play and winning. In fact, bad teams have better punting statistics than good teams, because they punt often and typically punt into a longer field. Even field-goal accuracy has little correlation with winning.

Combination Metric Correlation to Wins
Point Differential 93%
Yardage Differential 79%
Passer Rating Diff 73%
Total Penalties 3%
Time of Possesion 46%
Turnover Ratio 69%

A good offense can lose games because of a bad defense, and vice versa. Therefore, statistics that combine offensive and defense performance have a higher correlation to winning. Point differential has the highest correlation (93%) of any metric I analyzed. Because of the importance of the passing game, passer rating differential also has a strong correlation, as does the often-discussed turnover ratio. Curiously, good teams and bad teams seem to have a similar number of penalties.

In case the above analysis seems like statistical mumbo-jumbo, let's take a look at the performance of the top teams in the NFL, those that recorded 10 or more wins in 2009. This table shows where these teams rank in the NFL (1-32) on several important metrics.

Team Regular Season Record Net Offensive Points Net Defensive Points Yards per Pass Attempt Yards per Rush Attempt Opp Yards per Rush Attempt Opp Yards per Pass Attempt
Indianapolis Colts 14-2 6 11 4 30 19 4
New Orleans Saints 13-3 2 10 2 7 26 20
San Diego Chargers 13-3 4 9 1 32 24 13
Minnesota Vikings 12-4 1 13 8 22 6 16
Dallas Cowboys 11-5 13 3 5 2 9 10
Green Bay Packers 11-5 3 6 10 13 2 6
Philadelphia Eagles 11-5 7 16 11 14 11 5
Arizona Cardinals 10-6 11 19 12 23 25 11
Cincinnati Bengals 10-6 23 7 20 24 7 7
New England Patriots 10-6 5 5 6 21 23 19

As you can see, all of the top 7 offenses in net points scored appear on this list, but only 4 of the top 7 defenses. On yards per pass, 7 of the top 8 teams made this list, but on yards per rush, two of the worst teams in the league won 13 or more games. For stopping the pass and stopping the run, the record is mixed, but the top teams rank a bit better in stopping the pass.

 

In summary, the 2009 data show:

 

  • Passing is more important to winning than running.
  • Offense is more important than defense.
  • The critical measure of an offense or defense is points (preferably net points), not yards.
  • Interceptions and sacks are important.
  • Fumbles and penalties are random events that are statistically unimportant.
  • Special-teams play is largely irrelevant to winning.

In Part Two of this post, I will use the above metrics to analyze the Steelers 2009 performance and determine what improvements will most likely result in an improved winning percentage.

Net Punting is negative

Wouldn’t that say that teams that punt the ball backwards have a better chance of winning?

"Sick Puppy is ultimately as unforgiving as nature's order... There is no redemption or apology." - wikipedia

by Sick Puppy on Jan 10, 2010 7:50 PM EST reply actions  

The correlation is negative, meaning that teams with a better punting average actually win fewer games that teams with a worse punting average. As Klompus says, statistics can only be taken so far. Obviously, punting backwards is not a good idea. But the point is that investing a lot of effort (or a significant portion of your salary cap) in a Pro Bowl punter will not win many games for you. (Case in point: the Raiders and Shane Lechler.) Putting that effort into other portions of the game is more likely to produce wins.

by Steelin on Jan 10, 2010 8:03 PM EST up reply actions  

Right – according to the negative correlation, it would benefit a team to punt the ball backwards thus guaranteeing the worse net punt average. You would win more games.

correlation =/= causation

by hasay on Jan 10, 2010 8:19 PM EST up reply actions  

agreed – Net punting average is probably not a good statistic to use for correlation of winning. The teams that win generally have better offenses. Better offenses will punt the ball closer to the opponent’s goal line. Therefor, the net punting average will be lower because there is a limit to the maximum.

It doesn’t mean that you shouldn’t get a good punter. A good punter will be able to maximize the net punting average by directional punting or increasing the hang time. Shane Lechler averages high net yards because he is playing on a team with a poor offense. (He is a good punter as well)

Consider

In situation A, the team is able to drive the ball to the opponents’ 40 yard line but come up short on 3rd down. The punter will try to place his punt inside the opponents’ 5-yard line, which would be a 35-yard punt. If he doesn’t succeed, the likely result will be a touchback, which would be a 20-yard punt.

In situation B, the team is not able to drive the ball into the opponents’ territory and punts from inside their own territory. In this situation, the punter will just boot it as hard as he can, which will result in a 40-to-50-yard punt, pending a return.

Good offenses will find themselves in situation A more often, and bad offenses will find themselves in situation B more often.

offense finds themselves in situation A far too often than they should. When they should be scoring points.

This

the other part of the explanation is that if your offense stinks you get more value out of a good punter, so losing in other areas causes teams to invest more in the punting game. Over the last decade most of the leagues top punters have been on average or bad teams.

by SteelerFan Ben on Jan 13, 2010 9:45 AM EST up reply actions  

One could also say that over the last decade most of the league’s bad teams have had the top punters. This would be looking at stats like net yards and average yards. There are many punters who can kick the ball far.

Most teams will not draft or overpay a punter to compensate for a bad offense. Only the Raiders come to mind here.

That was 10 years ago

I haven’t run the same statistics for previous seasons, but it is clear from watching the games that the NFL has become more pass-dominant over the past decade. We should be planning for the future, not the past.

by Steelin on Jan 11, 2010 11:40 AM EST up reply actions  

While I agree with a lot of your arguments, I disagree with any “get with the times” statement. Good Football wins games.

The inordinate amount of success the Steelers have had in the last 40 years is largely due to the organization ignoring fads and trends and focusing on playing good football.

I agree the passing game is more of a focus in the NFL right now, but that doesn’t mean that thinking for the future we need to become more pass oriented. We need to run a balanced offense that makes the best use of our talent. You run that and execute and it doesn’t matter if your offense is pass or run.

by Phantaskippy on Jan 11, 2010 1:46 PM EST up reply actions  

It’s not a fad if it’s related to rules changes. They are playing a different game than they did in 2002. NFL teams have to build their team to use the rules to their benefit and if the way the game is called changes they need to adapt.

by SteelerFan Ben on Jan 13, 2010 9:48 AM EST up reply actions  

rules change all the time, it’s the nature of the game. You adapt to fit the rules, you don’t rewrite the book.

by Phantaskippy on Jan 14, 2010 4:40 PM EST up reply actions  

You're right of course.

The stats back up what we see unfolding on the gridiron every week. Teams win with passing, not running. Running has become about what the pass used to be—a change of pace to keep the defense honest. But having a credible short-yardage runner is still important. I think most Steeler fans would love to have Bettis back on the team (in his prime) for 3rd-and -short or goal-line situations.

It would be interesting to see a correlation based on running touchdowns to wins.

"Sick Puppy is ultimately as unforgiving as nature's order... There is no redemption or apology." - wikipedia

by Sick Puppy on Jan 10, 2010 9:05 PM EST up reply actions  

Here you go

Rushing TDs are 64%, passing TDs are 75%. The primary correlation is that TDs are points, and points are correlated to winning. It doesn’t make much difference whether you score by running or passing, but as you can see, the statistics still favor passing slightly.

by Steelin on Jan 11, 2010 12:49 AM EST up reply actions  

Is this total TDs or net TDs or some other metric?

"Sick Puppy is ultimately as unforgiving as nature's order... There is no redemption or apology." - wikipedia

by Sick Puppy on Jan 11, 2010 6:48 AM EST up reply actions  

The previous figures were for rush/pass TDs scored. For the defensive side, it is 60% for rushing TDs and only 21% for passing TDs. I hadn’t noticed that discrepancy before. Possibly, good teams get ahead and force the opponent to pass a lot and therefore score fewer rushing TDs, whereas bad teams fall behind and the other team can keep handing off the ball. The same effect happens with rushing/passing yards allowed. That’s why I focused on yards per play, which eliminates the differences in pass/run ratio.

by Steelin on Jan 11, 2010 11:56 AM EST up reply actions  

I'll put it that a reliable short-yardage back is now more impotant than EVER

In this pass-oriented league the ability to get four yards on every run is key.

Hence the value of a Toby Grhart in the upcoming draft. A guy who can move the chains with continuous four yard runs is a clock-killer and defensive nightmare. The days of the “big-play” back are over.

by tobiathan on Jan 11, 2010 4:34 AM EST up reply actions  

What is your evidence for this?

Look how quickly the “best running back in the NFL”, Adrian Peterson, was neutered when the Vikings got a good quarterback. Teams don’t move the chains any more by running four yards at a clip. A clock-killing offense can easily consist of short passes, screen plays, and draws mixed with occasional straight runs to keep the defense off balance. When a guy can walk in off the street and gain 178 yards in a game for the Browns, it shows how little value there is in overdrafting or overpaying a high-end RB.

Because that how it sounds.

Sorry, I thought you were suggesting using a high draft choice on a premium RB like Gerhardt. I, too, would like the Steelers to have a “big” back that could convert short yardage, but a guy like that can be acquired inexpensively.

Right

The Titans probably couldn’t trade Chris Johnson if they tried

by SteelerFan Ben on Jan 13, 2010 9:50 AM EST up reply actions  

The Titans were 0-6

with Johnson too.

Big-play RBs aren’t what you want for a team that wins consistently.

Cowher’s teams were constantly good because they ate up clock and could hold a lead after scoring. Of course, his teams lacked the pass-play ability of a Big Ben offense for most of his tenure and were therfore too one-dimensional to win the big games when opponents pulled out all the stops and successfully completed deep pass-plays.

Arguing that Chris Johnson wins games is inaccurate; the ability to make the play in a given situation wins games. Situational football. In some senses a “balanced attack”, but more accurately it is the ability to control the clock(and thusly keeping the other team from scoring) AND scoring more points than opponents.

Simple, but nonetheless very difficult.

by tobiathan on Jan 13, 2010 12:08 PM EST up reply actions  

Actually just the last part

There’s lots of way to get to “AND scoring more points than the other teams” and that is the only thing that matters

With regard to

Situational football. In some senses a "balanced attack", but more accurately it is the ability to control the clock(and thusly keeping the other team from scoring) AND scoring more points than opponents.

Cowher’s teams that were so good at sealing the deal when up by 10+ often gave the opponents 3 or more drives in the 4th quarter, the difference is their defense made the stops. Despite our lack of a power back, our defense this year had the 3rd least plays run against and the 4th least time of possession against. How much less time does the O need to give them to find this winning formula?

by SteelerFan Ben on Jan 13, 2010 1:22 PM EST up reply actions  

You can read TOP both ways

Maybe the Steelers had the third-least time of possession because the defense forced a lot of three-and-outs. I would like to see “time per possession”, in other words, the average time of each drive. But I have never seen that stat posted anywhere.

by Steelin on Jan 13, 2010 4:41 PM EST up reply actions  

I agree, actually plays per drive would be a really good metric to look at for the whole game scenario, and time per drive for both sides in the 4th to get the clear picture.

Part of that is the return touchdowns as well, that’s a BAD way to keep the D off th field, and when you do it as much as we did it’s bound to have some effect on overall TOP.

However, one point that we don’t need that level of detail to see is that if the defense was falling apart in the 4th because they were tired or on the field too long. That is an indication that they’re too old or were just lacking in conditioning due to camp cupcake in the summer, can’t blame that on the O which held the ball for 33 minutes a game. I don’t think beefing up the running game so the O can get from 33 to 35 is going to be the answer either, but I can understand some people might have a different opinion.

Statisically speaking...

You can find exceptions to any rule. These statistics just give the broader trends. Also, if you take any rule to the extreme, it can break down. After all, as Blitzburgh described in an earlier post, the Steelers’ special teams in 2009 were one of the worst in the NFL over the past ten years. But even with historically awful special teams, the Steelers had a winning record and nearly made the playoffs. And in fact, they could have won the KC game despite giving up the kickoff return TD, if they don’t have two interceptions.

by Steelin on Jan 11, 2010 12:55 AM EST up reply actions  

Right

but still you can’t say that Special Teams is largely irrelevant because while its true if we don’t have two interceptions we win, it is also true that even with those interceptions we win if we don’t give up the Special Team Touchdowns. I believe that all three phases are equally important but you notice Special Teams less because they aren’t on the field as much. but they can effect the game just as much as offense or defense.

Running

Thanks for that great statistical analysis, but, Statistics Can Hide a Multitude of Sins.
While I’m dealing with a small sample size (only 4 games) it should be noted that those teams advancing in the playoffs ran the ball and some ran well. That is, those teams that ran much better than their opponents won by 19 points. Dallas and Baltimore both ran more than 100 yards better than Philly and New England. In point of fact the running game of Baltimore was so much better than the Pats that it hid the miserable passing performance of unibrow and because of that they were able to beat an excellent passing team and quarterback quite handily.
I’m not disputing any statistics but it should be evident that if BA had a good running game e.g. a fullback (running and blocking) plus a decent offensive line (both pass and run blocking) and also utilized them,we would probably be in the playoffs.
BA will probably never go back to the run heavy offense of the past (just like the rest of the NFL), but the ability to run would really set up the pass.
Thanks for letting me vent my spleen!

There is an interesting theory

that passing wins in the regular season and running wins in the playoffs. The Jets and Ravens are certainly the exceptions to the “passing” rule, being old-school run-first teams with top-ranked defenses. If the Jets and Ravens continue to advance, and if the Colts and Saints are one-and-done, it would give credence to the theory that the playoffs are different from the regular season. But 4 games is certainly too small a sample size to tell. (BTW, was there any running in the GB-Ariz game?)

One year does not prove anything

If these stats were for the last 4-5 years, I would say ok. But one year does not prove anything. Look, are the Bungles a dominent team? Are the Saints unbeatable? If Peyton Manning would get hurt, how good would the Colts be? If Curt Warner retires, will the Cards make the playoffs next year relying on Leinhart and a wide open passing game. A running game may be enough. You have to be able to run and pass, play defense and have solid special teams.

by Steeler Nation VA on Jan 11, 2010 7:57 AM EST reply actions  

Are the Bengals dominant? As the table above shows, they rank 23 in net offensive points, worse even than the Jets, and their defense isn’t even very good. It is a mystery to me how they won 10 games. Let’s call them an outlier.

Are the Saints unbeatable? Obviously not, but they did win 13 games before they stopped trying. They have an explosive offensive and an opportunistic defense that scored an incredible 8 TDs during the regular season. Let’s see what happens in the playoffs.

How good would the Colts or Cards be without their star QB? Obviously, not as good. One problem with relying on the passing game is that the QB becomes by far the most important player on the team. If he is injured, or even has a bad day, the team is likely to lose. But statistically, a team with a good QB is more likely to win than a team with a good running game.

If you want to argue that a good running game is enough to get into the playoffs, talk to the #1 rushing team of 2009, the Tennessee Titans. Or the Panthers (#3), Jaguars (#6), or Chiefs (#8). Heck, the Rams with Stephen Jackson ranked #11 in yards per rush, and they won only one game. In contrast, the top 10 teams in yards per pass attempt all finished at 8-8 or better, and 7 of the 10 made the playoffs.

Interesting and well constructed stat post

I don’t agree with some of the arguments. Like Klompus said, it simplifies the game too much. Passing and running, go hand and hand. If you can run the ball well you will be able to throw it easier, and vice versa. Also, I don’t agree with the fumbles having that small of an impact. Did you do fumbles or fumbles lost? I can’t imagine how drive-ending turnovers would have such a low impact.

Did you break down the stats for all 512 games individually or did you just use season stats and team records? I’d bet this analysis would say two completely different things for those break downs.

Well done post though, rec.

Optimism. Positivity. Win.

by John Stephens on Jan 11, 2010 8:40 AM EST reply actions  

Thanks Johnny

I looked at fumbles lost. Although losing a fumble is obviously a bad thing, the point is that good teams and bad teams fumble at about the same rate. Furthermore, good defenses and bad defenses “cause” fumbles at about the same rate. So I conclude that NFL players, on average, are equally well coached to not fumble the ball, and that fumbles occasionally happen anyway.

I just used season stats and team records. Certainly, in any particular game, a big play (lost fumble, interception, return TD, etc) will often determine the winning team. But over the course of a season, these types of plays don’t happen very often and tend to even out. The one exception is interceptions, which clearly vary depending on the skill of the quarterback and less so on the skill of the defense.

Another way to look at these numbers is to pretend you are the coach or GM. Where can I invest my coaching time or salary-cap money to improve my winning percentage? For example, we know injuries are pretty random, so there is no point in worrying about them even though they can clearly affect a team’s success. Fumbles are the same way—they just happen.

The statistics also show that investing in special teams is not warranted, although you clearly need to have them and ensure that they are reasonably competent. The running game is the same way—you need a competent running game to set up the pass, but investing to improve the running game is not likely to improve success. On the other hand, improving the passing game is more likely to result in winning more games.

by Michael Bean on Jan 11, 2010 5:45 PM EST reply actions  

Agreed - good stats, but...

The most obvious reason for the statistics to exist as reported lies in the continued focus on passing offense by the rules makers and enforcers. The Steelers have moved to the passing game in the belief that it is a) easier than ever to pass, b) they have a good QB and c) the offensive line doesn’t even have to be that good to produce big plays in the passing game. All of these things are true as a whole. It is easier to pass when the line gets to hold much more than even 5 years ago. It is easier when defensive holding, illegal contact and pass interference are called with less contact than ever before. And it is true that BB is a good QB with a strong arm and the ability to make plays.

All 3 of those things are true. The NFL has embraced tackle football – but mostly for the offensive linemen!! We all witnessed Harrison being mugged repeatedly with no calls being made for the whole season. The league is promoting and directly influencing the style of play, the type of players being chosen- including offensive linemen, and the minimizing of defense for the most part. In other words – they are continuing to embrace the NBA model for the sport. Scoring = Viewing.

My only disagreement lies in the trend being quite so impactful in the playoffs. Running the ball effectively is more important in the playoffs for two big reasons – defenses in general are better and generally, teams get more conservative the bigger the game (Arizona Cardinals may be the exception here). With better defenses you need to be more balanced, more capable of running and passing. Also, with most teams taking less risks in the playoffs – the tendency is toward less scoring rather than more. A team’s running game comes in to play when you are inside the 5-10 yard line. Those TDs scored instead of FGs can be the difference in winning and losing even more than the regular season.

Let's not forget there is only one important statistic...

and that is, at the end of the game, in order to win you need at least 1 more point on the scoreboard than your opponent. And that correlation to wins is 100%. How you acquire those points is irrelevant.

Good work on the stats Steelin, I think your data does show something, but it’s probably not what you think it showed.

First off, I think many if not most of us on this board have at least played the game at some level. So, we should all know that it’s a silly statement to say that “offence is more important than defense,” or that “special teams is largely irrelevant to winning”. Everything each unit does on the field during the game is important to winning and losing, and what each of the 11 players on the field does is important. Any coach would tell you the most important thing is execution. The team that plays better usually wins.

Let’s take the Raider game as an example, our O (particularly passing game) did their part and put us in a position to win the game. However, the D allowed a poor passing team to march down the field and score the winning TD. It was poor execution on the part of our D that
caused that loss. Offence and Defense are equally important, if you can’t stop a team from scoring when you need to, then you aren’t going to win.

Special Teams play is always important because it involves a change of possesion. You are either punting or kicking off the ball to the other team (reliquishing possesion) or receiving it (acquiring possesion). If you do your part poorly it can result in poor field position (either way) or worse case points for the other team. Same goes for FG kicking, you are either going to score points or you are going to relinquish the ball to the other team…worst case being they block it and return for a TD. How many times in the NFL have we seen a missed FG cost a team a game? I’m sure there are plenty (more than 3%).

As for fumbles, depending on their timing, they can be critically important…just ask Aaron Rodgers about his in OT in the Ariz game. Same thing goes for penalties, remember what Ryan Mundy did against the Raiders that gave them 1st and goal at the 1.

Going back to what I had eluded to earlier, I do think Steelin did uncover something that maybe we already knew…and that is…passing has become more prominent in the NFL now more than ever. That’s mainly due to the rules that have evolved to protect the QB at almost all costs. Included in that is what’s not considered holding these days…just ask James Harrison. On the flip side, receivers can’t be touched beyond 5 yards and helmet-to-helmet contact penalties eliminates some of the intimidation from DBs. The NFLs competition committee has openly tried to make the game more high scoring to attract the more casual audience who are more likely to tune in for a Manning/Brady or Rodgers/Warner shootout than a Steeler/Raven grind-it-out 13-10 game.

So, teams with the top QBs are going to have an advantage in terms of execution in the passing game, and may be better able to take advantage of the rules. On the flip side, some of the teams that Steelin cites that had good running games but weren’t winners (Titans, Panthers, Jags, Chiefs, Rams) are teams that had below avg. QBs and premier RBs (C. Johnson, D.Williams, Jones-Drew, S.Jackson), so naturally they would rely more on where their talent is. The Chiefs got good production from their RBs as well.

In summation, as it pertains to our beloved Steelers, we have both a great QB and a very good RB, so we should be able to win either way (passing or running). However, the real key to returning to SB form is improving the D and STs which are equally important to winning.

It’s not that hard if you know how to use spreadsheets. I just cut and paste the stats from nfl.com.

The Bettis running game had an additional effect

That does not show up in Stats lets look at the 3rd and 4th quarter with the Steelers up by 10 and Bettis in the backfield what play does the defense expect… a run of course and that is what they get and yet they can not stop the Steelers from marching down the field chewing up clock even if we stall at mid field then pin them deep we have imposed our will on them anything more than 3 and out is demoralizing and a sense of panic starts creeping into the offense that is only down by 10 half way through the 3rd quarter. Teams no longer feel like they can play their game plan they go into we have to make something happen mode take deep drops and try to make big plays which allows our defense to dominate. The QB stands in the pocket too long trying to get a receiver open for the 40 yard pass and ends up getting sacked or forcing the ball for a pick. Not to mention we have drafted our o-line and defensive players based on that style of offense.

I think Ben is an Elite QB can make things happen can make all the throws worth every penny he makes for his leadership and skills, however I do not think just because we are paying him 100 million that we have to get 40 passes a game out of him just because of it. I liked it better in the 05 season where we came out throwing put up a lead and then pounded the ball where a win meant that Ben only threw 25 passes not because he wasn’t capable of winning the game throwing more but because that was all he needed to throw. Protect that investment If the game is on the line Ben is THE MAN why not extend his career by letting him do what he needs to win the game that is what won us 2 SB’s with Ben it’s a team sport do not put all our eggs in one basket make teams fear our running game again and help to keep ben’s jersey clean.

Agree 100%

This is what we have all preached all year. Get a lead. Run the ball and eat up clock time. Let the defense get in their starting blocks and blitz and put pressure on the QB and play defense.

3 passes and out just puts the defense back on the field with no rest. 3 runs and out atleast eats up clock time and gives the defense a rest.

We have a back who rarely gets tackled for a loss. If he is hit behind the line her has the power to get back to the line and gain a yard or two. Use him.

Thanks for the feedback

In my original post, I overstated things to make a point. Of course, good teams can’t ignore any of the three phases of the game. Offense, defense, and special teams all must contribute. And I agree that, in any given game, the difference between winning and losing can come from any member of the team or from a random event such as a fumble, missed FG, or blown call by a referee. There are many ways to win a particular game, and there are even different ways to build a winning team.

What I think these numbers show is that the NFL has (probably intentionally) shifted to favor offense over defense and passing over running. We can argue over whether this is a good thing, but the fact remains that the shift has occurred.

In an era when every personnel decision and many game decisions are governed by the salary cap, it is critical to build the team in a way that gives it the best chance to win games. In a league that encourages passing, the team should be built to pass first and run to set up the pass. The defense should be built to stop the pass first and the run second. The team needs competent special teams but should not overpay for a top-flight kicker or punter. In these ways, the team can make most effective use of its salary cap.

Part 2 of my analysis, which provides the Steelers rank in these categories, is now available.

Good Stats But...

You go with what works… It’s not about running or passing. It’s about ball control. Our offense didn’t do a great job of ball control this season, so no wonder the defense was winded at the end of games…

Rush yards versus attempts

My personal theory is that the yards that you gain might not correlate very much with winning, as you suggest in your post, but that the attempt to run might correlate in a stronger manner. There are two factors: first, the attempt to run takes the defense out of passing game, even if only slightly, or temporarily, making play-action more useful; second, a team will naturally (or should, in any case) run more if they are ahead in the 2nd half and trying to kill the clock.

Would you mind plugging in rush attempts in your spreadsheet?

Already done

Rush attempts have a 12% correlation with winning, which is pretty low. Pass attempts have a 14% correlation, so what’s really going on is that good teams run more offensive plays. I have also computed run/pass ratio, and there is a tiny (4%) correlation in favor of more running plays. But as you point out, teams that are ahead on the scoreboard are likely to run more often, particularly in the second half of games, so that would skew the data in favor of rushing.

I would like to see stats on run/pass ratio in the first half of games, as I think that would be more indicative of the style of offense that each team plays. By the second half, offensive playcalling becomes more situational. But I have not seen that kind of breakdown by half—if anyone has access to such information, please post a link.

Not suprised or dismayed, but highly sceptical.

So when we pick our 53 player roster this year, we can eliminate running backs and special teams players, as they do not have have a direct “correlation to wins”. Do we need to even field a defense, to help our correlation to wins?

As I said above, you can’t ignore any part of the game. The point of these stats is to show that you can win with mediocre (or even bad) special teams and running game, but teams that focus on excelling in the passing game and stopping the pass have the best chance of winning. Conversely, teams that focus on excelling the running game (e.g. Titans) are less likely to make the playoffs unless they also excel in other areas.

I agree that you need to do more than one thing well.

I think on offense, you need to be balanced. Doesn’t matter if you run first or pass first, as long as you have the ability, and willingness, to do either, in the majority of situations.
