I just want Ferentz to embrace the notion that "balance" doesn't mean a 50/50 run to pass ratio. Balance should mean that out of any given formation/set you are a threat to either run or pass the ball. Iowa virtually never throws out of its spread looks. It almost never runs on 3rd and anything more than 3, I don't think they've ever spread the field and ran on short yardage situations, and can't recall the last time they ran a play-fake on a 3rd and short. If Iowa comes out in shotgun bet the farm it's a pass regardless of down and distance.
I think they also need to scrap this idea that as QBs get older in the system they are no longer allowed to run. I suspect Tate, Stanzi and Beathard's carries all greatly decreased from their sophomore to senior years. The QB needs to be able to keep a couple drives per game alive with his feet, and having him sit back in the pocket with instructions not run isn't going to keep him healthy if he is getting hit on every play back there.
