Michigan’s offense is essentially one giant question mark heading into the 2020 season. There are concerns about just about every position group on that side of the football.

Four of the starting offensive linemen from last year’s team are gone. Three of the four leading receivers have departed. A new quarterback will take over under center.

That’s an awful lot of change even in a standard year. Clump that together with the loss of spring practices, a whacky summer training schedule and a large gap between padded practices, and it could be somewhat of a nightmare scenario for Jim Harbaugh and the Wolverines in the early portion of the upcoming season.

But the head coach remains confident with the group. Talking on Inside Michigan Football on Monday night, Harbaugh likes the competition he’s seeing at the QB position, and how well the offensive line has come along so far.

“The quarterbacks have been very good. The offensive line is coming together well,” Harbaugh said, according to Angelique Chengelis of The Detroit News. “The group we’re really excited about is the running backs. Ready to let it rip on offense.”

If there is one stable position group for Michigan, it’s definitely the running back corps. That group includes experienced backs Zach Charbonnet, Hassan Haskins, Chris Evans and Christian Turner and should be a strength for the Wolverines in 2020.

As for the rest? As confident as Harbaugh is, that question mark won’t be going anywhere until we see the offense in action on Oct. 24 against Minnesota.
