Crossing routes aside, Michigan's defense has been feasting on the weaker offensive opponents while at the same time they have been getting roasted by the top tier teams.
This has happened time and again over the last 5 years.
Also at the same time they haven't had an offense to score at will to keep them in games. It should never be ok to score 39 points and still get beat by 3 scores. With a top 10 defense I might add.
I'm not going to say that DB has become a fall guy but I do think it was time for him to go.
