Just a quick look at the gains from all RB in the last 2 games.

Before I start I just want to point out that obviously all three backs are playing with and against different levels of personnel, in different phases of the games.  

From the Denver game Dwyer was looking good on the box score but he really didn't have a lot of positive plays.  The box score usually shows an average yards per carry.  It's a decent stat if the back has consistent production but it makes boom and bust players look better than they actually are.  For those that speak Stats:  Average is the best way to asses typical production from a data set with a normal distribution.  For the non normal, you are better off looking at median or % achieving success by some standard.

"Splash Plays" as Tomlin calls them are great and can change a game.  In many cases however you need the run game to eat some clock, take some yards on first down or simply move the sticks on a 3rd down.  Steeler Football if you will. 

I took a look at some better stats to get an idea of how well suited Mendenhall, Moore, Redman, and Dwyer are to this role.

I took all running plays into account per NFL.com play by play stats including some that were overturned by penalty.  I calculated Average YPC, Median YPC, % of plays with yardage less than 0, % of plays with yardage from 0 to 2, and % of plays with yardage of 3 or more.  (Median is the number with equal # of data points on either side of it)

The stats back up Dwyer's boom or bust nature in that he had a good play (3+ yards)  less than half of the time. The other backs show fairly similar numbers for these two games anyway.  Redman Mendenhall and Moore all got 3+ yards at least 70% of the time.  Redman's stout running is reflected in his pack-leading median yards per carry of 5.0.
