Notre Dame, however, plays No. 8 Oklahoma this week and closes the regular season against USC.
Which undefeated school emerges from all these matchups?
Chances are the system will wean out the weakest, although it doesn't help that Oregon, Kansas State and Notre Dame don't have any head-to-head matchups.
--They should get T-shirts made: The 22 points Towson scored at Baton Rouge on Sept. 29 remain the most points Louisiana State has given up in any game this season. The closest to Towson's 22 was 21 scored by South Carolina on Oct. 13. Towson is an FCS school from the Colonial Athletic Assn. LSU defeated Towson, 38-22. Towson's record dropped to 3-4 Saturday after losing to Old Dominion.
--Oregon State is 6-0 for the first time since '07 …1907. The Beavers played only a six-game schedule that season and defeated Astoria, Whitman, Pacific, Oregon, Willamette and St. Vincent College. Oregon State outscored the opposition, 138-0, which included a 4-0 defeat over the rival Ducks from Eugene.
The Beavers earned their sixth win this year with a 21-7 win over Utah in Corvallis.
Oregon State, which finished 3-9 last year, is already bowl-eligible for 2012. "It's just a start and we will see how good of a bowl game we can go to as the season goes on," Coach Mike Riley said.
--Notre Dame has won four of its seven games by a total of 20 points. "The mentality now is we are going to do whatever it takes to win," linebacker Manti Te'o said after a three-point win Saturday over Brigham Young. "It's no longer just crossing our fingers and going 'please, please, please,' waiting for the other shoe to drop."
--West Virginia has given up 212 points in its first four games as a member of the Big 12. Remarkably, the Mountaineers (5-2 overall) are 2-2 in conference play despite consecutive losses in which they were outscored 104-28.
"We didn't forget how to coach and this program didn't forget how to win just because we lost two games," West Virginia Coach Dana Holgorsen said.
--Texas "bounced back" from a 63-21 loss to Oklahoma last week with a 56-50 win over Baylor. In victory, the Longhorns slipped to No. 107 nationally in total defense.
"Coach [Darrell] Royal told me a long time ago the only games that are important at Texas are the games you lose," Texas Coach Mack Brown said after the Baylor win. The Longhorns improved to 5-2 and travel to hapless Kansas this week.
--Louisiana Tech (6-1) rebounded from a 59-57 loss to Texas A&M with a 70-28 victory against Idaho. The Bulldogs, who lead the nation in scoring at 56 points per game, have scored at least 56 points in five of their seven games.
