Yeah, they were knifing through on runs. I think it was often them recognizing run so quickly, it almost looked like a blitz sometimes.They were knifing in their linebackers avoiding blocks all day. They were hitting gaps in our zone blocks. Could have been stunts or delayed blitzes. Most of that is mental mistakes, but Utah States DC had a very good game plan.
On straight blitz in passing downs, Iowa did a very good job. Either that, or they only blitzed once or twice.
