It sounds like Michigan is trying to bring back Fisch for at least next year, but I wouldn’t expect him to be here much longer than that. I think he wants to get back to the NFL, and he’s never spent any more than 3 years at any job, IIRC.
I agree with regard to Brady Hoke. He recruited better than he gets credit for, because there are some talented guys that he just couldn’t develop. He also retained players, so now Michigan has some experience and depth for Harbaugh to work with. Although there will be some departures here in the off-season.
