Jim Donnan's Viewer's Guide

With so many big games on the schedule, Jim Donnan breaks down what to watch for this weekend.

No. 20 Notre Dame at
No. 3 Michigan
Saturday, noon ET
The Fighting Irish-Wolverines matchup will feature two high-powered offenses and two defenses with question marks. The team that does the best job tackling in the open field will have a big advantage. Whenever you get one of these big offensive matchups, the defenses always seem to get a burr in their saddles and play better.

The other key will be quarterback play. Michigan's Chad Henne and Notre Dame's Brady Quinn not only will have to make the big play but also will have to avoid the big mistake.

As well as Notre Dame played against Pitt, the Irish will have to throw the ball downfield more against Michigan. Teams will start playing more man-under coverage against them and pay more attention to the backs. Michigan must continue to keep its offense balanced between Henne and RB Mike Hart. Steve Breaston's return ability could be the difference for the Wolverines.
