After a disappointing performance last weekend in South Bend, Michigan returns to Ann Arbor to take on Western Michigan on Saturday in the home opener.

We’ve identified five things that you should keep an eye on during the contest.

Michigan’s Third Down Defense

Last season, Michigan finished No. 1 in the nation in third down defense, allowing opponents to convert just 26.1 percent of the time, or 47 times on 180 chances. Notre Dame converted 7-of-15 third down opportunities, which comes out to 46.67 percent. In a 13-game season, that puts Michigan on pace to allow 91 third down conversions, almost double last year’s total.
