[15] Arizona State at [1] USC

3:30 p.m., pay-per-view

If you need proof that the Pacific-10 is loaded with quarterbacks, get your eyes on this game, because it may be your best opportunity to see ASU's Andrew Walter, who has the talent and experience to remain poised against USC. After throwing for 428 yards against Iowa, Walter completed just 47.6 percent of his passes and averaged 144 yards in wins over Oregon State and Oregon. Still, compare Walter (249.8 yards per game, 15 touchdown passes, 1 interception) to USC's Matt Leinart (237.4 yards, 10 TDs, 3 INTs). Throw in ASU's excellent pass defense, and the Sun Devils have a chance.

Missouri at [9] Texas

3:30 p.m., pay-per-view

Here is Texas Coach Mack Brown, not 30 minutes after the Longhorns lost to Oklahoma: "Missouri's not going to care that we lost this week." Congratulations, Mack, you found someone who didn't care. The Tigers, despite a slip-up at Troy, are quite real. They lead the Big 12's North Division, but their fate will be determined in this stretch: at Texas, home against Oklahoma State, at Nebraska. QB Brad Smith hasn't thrown an interception in his last three games. Texas QB Vince Young (8 for 23, 86 yards vs. Oklahoma) must give the Longhorns at least the impression of balance.

[23] Texas A&M

at [16] Oklahoma State

7 p.m., Comcast SportsNet

And the most important game in the Big 12 is . . . this one? Yep. The Cowboys are quietly putting together one of the best seasons in the nation, and a win would make them 6-0 for the first time since 1997. Vernand Morency (173.8 yards per game) leads the nation in rushing and has at least one touchdown in eight straight games. The Aggies' only loss came in the opener at Utah; they won their next four by an average of 34-10. This one likely will be decided by turnovers: OSU (17 takeaways, two giveaways) ranks first nationally in turnover margin; A&M (13, 1) is second.

[10] Wisconsin at [5] Purdue

5:30 p.m., ESPN2

Best game of the week? We think so, if only for all the yin-versus-yang story lines. No one can stop Purdue, which averages 509 yards of offense; no one can move the ball on Wisconsin, which allows just 198 yards, best in the nation. Purdue QB Kyle Orton hasn't thrown for fewer than 275 yards in a game; Wisconsin's defense hasn't allowed more than 230 yards of total offense in a game. The key matchup, though, is this: Wisconsin RB Anthony Davis, who has 381 yards rushing the last two weeks, against Purdue's run defense, which allows just 76 yards per game.

North Carolina at [11] Utah

10 p.m., pay-per-view

In theory, this and a Nov. 13 game at Wyoming (4-1) should be the significant hurdles for the Utes en route to a perfect regular season and, perhaps, a shakeup of the BCS. Utah QB Alex Smith (eight TDs, one INT) must be salivating at the idea of going up against the Tar Heels' defense, which allows more yards (476.3) and more points (33.8) than any in the ACC. Coupled with earlier victories over Texas A&M and Arizona, a win here would make the Utes 3-0 against BCS schools.
