After this year's disaster of a season, Michigan will be getting a new defensive coordinator.
I don't know if that is good.
Using NCAA total defense, Don Brown (the former defensive coordinator) produced great defenses in 2016-2019 (#1 in 2016, #3 in 2017, #2 in 2018, #11 in 2019).
But Michigan had the #88 in 2020. And they were blown out by Ohio State in 2018 and 2019.
It could very well be that Michigan is getting rid of a very, very good defensive coordinator whose demise is two particularly bad games and a perfect-storm season in 2020.
