It is all a guess, but the obvious part was that he was playing hurt for sure. I think the coaches felt he still gave us the best chance to be successful is why he played but they have been wrong before.
Hill hasn't looked great for sure and he was brought in because Iowa needed more QBs. Not sure if he will be better than Cade was playing hurt or not. But we are going to find out now.
No chin says it the Hill Era hop on and enjoy the ride.
