Here's a look at what to watch this weekend as Notre Dame travels to the Big House:
More Louis Nix: Nix impressed the staff in his debut in Week 1, notching seven tackles and 0.5 tackles for loss. Expect the big nose guard to be used more to try and make things difficult up the middle for Denard Robinson.
A calmer Brian Kelly: The head coach drew the ire of some with his sideline tantrums in Week 1, and he has vowed this week to do a better job of knowing when the cameras are on him. Kelly was able to joke about it Wednesday when asked if he would don a throwback outfit to match his players' uniforms this Saturday.
Speaking of which, what's that on the helmets?: No, Notre Dame won't all of a sudden look like Maryland in Week 2. But it will lose the plain helmets for ones with a shamrock on each end, in addition to slightly modified jerseys for the matchup. Michigan's meanwhile, will feature a block 'M' in the middle, with jersey numbers closer to the players' left shoulder pads.
