I don't know if I read it here or somewhere else, but I heard Wisconsin players say they knew the exact play Iowa was going to run when they were in a run formation.
The predictability of Iowa's offense against Purdue and Wisconsin was disappointing. Especially after seeing how Iowa had used the mis- direction well against MD and PSU.
The weird part is you could tell Brian Ferentz was running the same play 2 times in a row on many different occasions, and the play never worked the 2nd time.
Against Purdue, Iowa had a 3rd and 1, ran the QB sneak that failed then on 4th and 1 ran another QB sneak that failed again.
Against Wisc, Iowa had 3rd and 2, had a FB run that failed, then on 4th and 1, ran another FB run that failed again.
Its not just a crappy OL and an immobile QB, but that does not help. There is a lack of creativity and too much predictability in Iowa's offense.
