I will agree Iowa needs to blitz more and drop AC and Binns back into coverage at times! Also I wouldn't mind seeing Iowa sub in a LB at the DE position and drop him back into coverage at times. Arizona knew what we were going to do and they exploited it. They weren't worried about the deep ball, they wanted the 3 yd slants and the 5 yd across the middle patterns.
I would expect Norm to cook something up, because arizona gave the rest of the big ten a look at how to beat our defense. (now i'm not saying it was all the defenses fault that we lost, I'm just saying Foles looked pretty comfortable and was throwing to spots on the field, rather than to where his receiver was.) Giving up 15pts on special teams hurt and a pick six is never good! You are never going to win games by giving up that many points!
