One of college football's great rivalries will be renewed Saturday night in South Bend when No. 18 Michigan makes the short trip west to battle No. 11 Notre Dame. It will be the teams' second consecutive prime-time affair, coming on the heels of a memorable 35-31 Wolverines win last season in Ann Arbor.
The Fighting Irish enter the game at 3-0, their best start since winning eight straight to start the 2002 season. Michigan has rebounded from a loss to Alabama in the season opener to defeat Air Force and UMass.
Notre Dame has dropped three straight to the Wolverines, but has won four of the last six meetings in South Bend as well as the three previous night games in South Bend, the last coming in 1990.
Let's look at five keys for Notre Dame in Saturday night's showdown.
