One of the big question marks facing Michigan football heading into the 2020 season is the offensive line, where the Wolverines will be forced to replace four starters from last season.
Certainly, with three seniors, the Wolverines knew that would be the case, however, they also need to replace center Cesar Ruiz, who left early for the NFL and is now being projected by some as a first-round pick.
For Michigan football, that leaves a big hole to fill at center and really throughout the interior of the line as Ben Bredeson and Michael Onwenu are also gone.
