Before we get started, this is not a "fire Sherrone" post. I like Sherrone and he needs to continue to work his way into this job.
The biggest risk in hiring Sherrone as the Michigan Football Head Coach is that he didn't have any head coaching experience. That is a big leap for anyone. Michigan is a final destination job in college football and the top of the ring for many coaches. This job is too big for most coaches. It was too big for both Rich Rod and Hoke who had lesser head coaching jobs prior to Ann Arbor.
