They had 7 guys in the box and they were bringing a corner or an outside LB every down. The problem was he wasn't just coming up the middle. One time he came from the outside and caused everyone to bump out and our center missed his block. The next play he came right up the middle and their D-End got free forcing stanzi up in the pocket and they were waiting right there.
Arizona played aggressive defense all night, that is why they were able to stop Iowa's running game. I can bet the farm says Iowa learned from that and when Big Ten Play starts, you will see teams start to blitz iowa and KOK will have a few checks for stanzi to make and Iowa will beat the blitz. Also the RB's didn't help their cause several times they were trying to spin and juke their way, they just needed to hit the hole and get 3-4 yds a pop!
