UM does have a mascot (sort of), and it's Harbaugh
The Michigan Wolverines don’t have a mascot.
Or do they?
To promote its coverage of the NCAA Tournament, CBS Sports created an illustration featuring the mascot from every school in the Big Dance.
Representing Michigan? Jim Harbaugh, complete with No. 1 big foam hand.
During his tenure as Michigan athletic director, Dave Brandon floated the idea of introducing a mascot. “You can’t get your picture taken with a Block M,” Brandon reasoned.
But Maize and Blue traditionalists fought back, and the idea was shelved.
