Many times last season we saw Troy playing linebacker. Some of this was due to Vince Williams trying to grow into a role much too soon, but some of it was because we aren't really a 3-4 defense anymore. We spend most of the game in sub-packages because of read-option and spread offenses.
Gerry Dulac quoted Tomlin a few days ago saying that "The Steelers used their sub-packages in which they employ five or more defensive backs nearly 65 percent of the time -- an increase of 10 percent from the previous season, Tomlin said.
It may very well be that we didn't do very well against the run as a result. Defensive backs playing away from the line of scrimmage have a tough time making a tackle for a loss, and as we saw so many times last year, defensive backs will lost their battles with the OL and the "Gronk" style tight ends.
Folks have wondered where everyone fits into our defense after the draft. Our linebacker unit is pretty full: Worilds, Jones, Timmons, WIlliams, Spence, Shazier, Garvin, Zumwalt ,and Carter. Only three of those--Carter, Worilds, and Jones-- are listed as OLB's. (No idea what Zumwalt is).
We'll end up with a 5 LB package on running downs as an alternate to the 3-4 and a 5 DB package on passing downs. I think the proof is in the pudding. We drafted a lot of speedy linebackers lately to put on the inside of the line. They are better at lateral pursuit but still big enough to fight off a block.
Sorry if this isn't news to anyone, I just started looking into our sub packages and found it interesting. I think this is the direction they're heading.
