I was sitting behind the Iowa bench at the Rose Bowl. Sully was limping around and, obviously, was injured.
Most people know that while an athlete is warmed up, it's possible to play through an injury, even if it turns out to be a pretty serious injury later. But once you sit and the body cools off, then reality sets in. That happened to me in high school football. I injured my knee but kept playing. After the game the knee swelled, and I missed the last five weeks of the season.
Iowa, at every position, was manhandled at the Rose Bowl. It was men against boys that night. Everyone was getting crunched. Sully paid the price. Anybody who thinks otherwise is simply wrong, if you don't mind my saying so.
BTW: Stratton is the best QB available for Iowa, so KF goes with Cade, the guy who can't run or throw, over the kid who did a heckuva job at the Rose Bowl. Stratton led Iowa to a game-tying TD after spending the regular season playing LB on the scout team. The kid can throw, and the two third-down completions he made were two of the best passes an Iowa QB has thrown in the last five years. And he is capable of moving around in the pocket and of running when necessary, none of which Cade can do. And Stratton has eligibility left. Cade does not.
There is zero reason to start Cade. But that's KF for ya. He still doesn't know a QB from a lamp post.
