NEW YORK Notre Dame is a victory away from playing for the BCS title. Alabama and Georgia each need two and could have to go through each other.
A day after Oregon and Kansas State lost to give up control of the BCS race, the Fighting Irish (.9973) moved into first place in the standings for the first time.
Notre Dame (11-0), ranked No. 1 in both polls and by the computer ratings, needs only to beat slumping rival Southern California on Saturday in Los Angeles to earn its first trip to the BCS title game.
Alabama (.9333) and Georgia (.8763) also have rivalry games Saturday. The Crimson Tide hosts Auburn, and the Bulldogs play Georgia Tech at home.
If the favorites win, the Southeastern Conference championship game will be a national semifinal of sorts.
If form does not hold and there are more upsets such as the ones that took out Oregon and Kansas State on Saturday night, there are a handful of teams that could be in the mix.
Florida (10-1) is in fourth heading into a huge game at 10th-place Florida State.
Notre Dame, which last won a national championship in 1988, has lost nine of the last 10 against USC, with the lone win coming in 2010 in Kellys first season.
But the Trojans have been a major disappointment this season, starting at No. 1 and dropping to 7-4 after losing Saturday to UCLA. They also will be without quarterback Matt Barkley for the matchup with the Fighting Irish. Max Wittek will make his first career start after Barkley was injured at the end of the UCLA game.
If Notre Dame loses, it could leave a muddle of one-loss teams vying for a spot in the BCS title game, even opening up the possibility of a second consecutive all-SEC national championship game.
