FYI, that's just speculation.
Another thing, in the last three years, our defense "averages" out to be pretty darn good. Going from worst to first from 2010 to 2011 is remarkable indeed... unless you take into account where we were in 2009.
against the run, & improving across the board at the end of the season.
We lost half of our DL rotation before the end of our first game in 2011 (Bullman in the preseason & Barwin week 1). We only had one game all season when we started all three of our starting LBs (Cushing, Demeco, Diles)..... & Eugene Wilson obviously lost a step.
& while I didn't think much of Dunta Robinson's on field ability, starting a rookie & approaching the game with what appeared to be a "protect the rookie" philosophy didn't help.
Not taking anything away from Wade, I'd much rather Wade Phillips than Frank Bush..... but we also gave Wade Jj Watt (in place of Amobi Okoye), Conor Barwin, Cushing, and Jonathan Joseph & Danieal Manning (I'm sure those were Wade's idea as well right?)...
Look, the defense stayed healthy through 2009, they had a good year. Didn't stay healthy through 2010... didn't look good. Stayed healthy (mostly) through 2011... they looked good. Football Outsiders called it
before the 2010 season (6 wins, because of defensive injuries).
