People already nailed it. Pretty easy to stop the run when there isn't much threat in the passing game. It also seems like we run better when the play doesn't take 100 years to develop. That seemed to be a better adjustment between Oregon and UF (what little we can take away as a positive from those games).
They haven't been taught how to run block. They don't fire off the ball like good run blocking teams do.. 3 or 4 of them will be on NFL rosters regardless.
This, Chaney was all about getting his OL the best pass blockers and disregarding run block training.
