The defensive line will dominate
It's going to be the final game at the Big House for Mason Graham, Kenneth Grant, and Josaiah Stewart. I really don't see them going out with a loss.
Northwestern hasn't allowed a ton of sacks this season but the Wildcats don't only average 5.8 yards per passing attempt, which helps you understand why. They are 86th in tackles for loss allowed and Northwestern's offensive line is in shambles.
Michigan's defensive line should own the line of scrimmage. Maybe that means 4-5 sacks and a bunch of tackles for loss but that group will be the star of the show on Saturday.
