Western Michigan has Michigan’s attention. The Wolverines are coming off a disappointing loss at Notre Dame, and Western Michigan is riding some momentum after generating 452 yards and scoring 35 points in the second half against Syracuse. “We’re up and at it and on it, and we’re going to need to be,” Harbaugh said. “Watching the tape, they’re an extremely good football team. Whether they’re playing at home or on the road, they’re a very formidable team.” (AP Photo/Paul Sancya, File)

FILE - In this Sept. 1, 2018, file photo, Notre Dame defensive lineman Khalid Kareem (53) sacks Michigan quarterback Shea Patterson (2) in the first half of an NCAA football game in South Bend, Ind. Notre Dame junior Khalid Kareem found himself lost in the defensive line shuffle for most of his first two seasons with the Irish. Always buried on the depth chart, the Detroit native just wanted a chance to prove that he could become a regular contributor, and perhaps even a starter. A late-season surge in 2017 followed by a stellar showing in spring ball earned Kareem his chance at both. (AP Photo/Paul Sancya)

Back in 2012, Kelly's Notre Dame team ran the table during the regular season to set up a showdown with Alabama for the national title.

Now Kelly's Irish are 6-0 and ranked No. 5 and look who is waiting them this week -- the Panthers. (AP Photo/Paul Sancya, File)

No. 4 Michigan might be without defensive star Chase Winovich for Saturday's showdown with No. 10 Ohio State because of an apparent shoulder injury. If he can't play, the Wolverines have so much depth they may be able to overcome it. The Buckeyes, meanwhile, have struggled on defense for much of the year. (AP Photo/Paul Sancya, File)
