Probably also earned the short leash in Colorado when he accidentally put his coaching down by saying that the back ups didn’t have to learn the playbook and all he did was freelance in practice
I wouldn't call it much of an upset. Anyway, the only teams left on their schedule that could move the needle are at Ohio State and home against Michigan. So they wouldn't be able to stack much in terms of notable wins.
Might just be me, but I would have gone for the two point conversion there. Iowa's offense hasn't been great and would be less worried about them needing two drives for field goals to win than one TD.
