Excerpted from MGoBlog:
The full accounting of Michigan opt outs who saw significant playing time during the season:

• RBs Kalel Mullings and Donovan Edwards
• WR Tyler Morris
• TE Colston Loveland
• OL Dom Giudice, Andrew Gentry, and Myles Hinton
• Edge Josiah Stewart
• DT Mason Graham and Kenneth Grant
• CB Will Johnson
• S Makari Paige

By contrast, Alabama’s lost a handful of rotation players in the portal—two of them to Michigan—but is largely intact. There is no way this game is a reflection of anything except the increasing absurdity of bowl games.
