Lloyd Carr is going to be 65 at the end of this month. Even a 2-year transition would put him at 67. Quite frankly, that's well past his prime. I've read somewhere that there is a significant drop in coaches' win percentage once they pass age 60. None of us want to see that.
Lloyd had his time. I'm not about to take anything away from that. But his time has passed, much like Yost, Crisler and Schembechler. It's time to move on.
