Now Notre Dame is ahead of Oregon in the BCS standings.
The Fighting Irish became the latest team to move past Oregon on Sunday, taking third place behind Alabama and Kansas State. The Ducks remained fourth.
Florida fell out of the top five with a 17-9 loss to Georgia, helping to set the field in the race for the BCS title game with a month to go in the regular season.
Alabama is locked in at No. 1, and if the Crimson Tide can keep winning it will play for its third championship in four years. The Wildcats (.9400), Fighting Irish (.9147) and Ducks (.9136) need to remain unbeaten, and keep an eye on each other.
The computers ratings are still holding the Ducks back because their strength of schedule lags behind the other contenders.
The Ducks are second in the Harris poll and USA Today coaches' poll, but ranked fifth by the computer ratings.
Kansas State is third in each poll and Notre Dame is fourth. But according to the computers, the Wildcats and Fighting Irish are tied for first.
Oregon's upcoming schedule could help solve the Ducks' problem. Oregon plays three opponents in the BCS top 25 (Southern California, Stanford and Oregon State) in its last four games, starting with the Trojans in Los Angeles on Saturday. The Pac-12 title game, if the Ducks get there, should give Oregon another quality opponent.
Notre Dame, with four games left, faces only one more team with a winning record (USC). Kansas State has three winning teams in its four remaining opponents, though only No. 25 Texas is in the BCS top 25.
