2021 Michigan football season preview: Running back

Continuing our series previewing the Michigan football team's 2021 season at each position, we look at the depth chart, strengths, weaknesses, question marks and make bold predictions for the Wolverines' running back room.In looking at the group's depth, we discuss the value of a three-back rotation, elaborate why all three backs could start in any given situation and assess the battle between Blake Corum and Donovan Edwards' similar roles. We then turn to the position group's strengths: Shaw takes a look at the physical strength of the room led by Hassan Haskins, while Lorenz outlines that Michigan should benefit from multiple years of landing its top recruiting targets.We also look at the room's weaknesses, taking a peak at Michigan's lack of a home-run hitter at running back, improvements to be made in vision and maybe some concern over a diluted rotation and limited carries. We also ponder what Edwards could bring in year one.We close with our predictions, looking at who might lead the Wolverines in rushing yards and how we think the position group will stack up compared to other position groups on the team and in recent Michigan running back history.
