The Wolverines have been great defensively this season, but they weren't tested by an offense the caliber of Alabama often.
Michigan allowed Maryland and Ohio State to score 24 points on them, and Bama should be able to do at least the same.
Alabama has scored at least 24 points in 12 of 13 games. Alabama QB, Jalen Milroe has been getting better, and is a threat with his arm and feet.
I also expect Michigan to be forced to be more aggressive in this game. I don't think Michigan will be able to simply get ahead and drain the clock, but I believe quarterback JJ McCarthy is capable of creating big plays

Total is too low
