Four questions for Michigan before Notre Dame test

Previewing the No. 20 Michigan football team's matchup against No. 8 Notre Dame, we look at four key questions we think the Wolverines must answer to come away with the win, then offer our predictions for the game.First, we look at whether the Michigan offense's solid second-half showing at Penn State is indicative of what's to come, or just a flash in the pan due to the Nittany Lions holding an early lead. In the discussion, we also look at why Shea Patterson and the offensive line improved, and what Notre Dame's defense brings to the table.We then consider how concerning Michigan's big-play defense is, and if the Wolverines can avoid lapses against a pretty balanced and dangerous Fighting Irish offense. Our final questions center around Michigan's challenge of emotionally bouncing back from a virtual title-eliminating loss, as well as why the Wolverines seem to show up so much better in big home games than big road games.Finally, we close with our over-under predictions and our final projections for how the game will shake out.
