Wisconsin at  Penn State
3:30 p.m., WJLA-7
This is the best matchup outside of Blacksburg, Va., and features a battle of co-leaders in the Big Ten. The key matchup will occur when the Badgers hand off to running back Brian Calhoun, who averages 135 yards per game on the ground, the fifth-best mark in Division I-A. Last week, Calhoun had 197 yards and a school-record five touchdowns in a rout of Illinois. The Nittany Lions, however, can contain backs of Calhoun's stature. On Oct. 1, Penn State held Minnesota standout running back Laurence Maroney to 48 yards in a victory. Wisconsin is the Big Ten's highest scoring team, so an offensive shootout is not out of the question.
Tennessee at  Notre Dame
2:30 p.m., WRC-4, WBAL-11
The importance of this game for both teams can't be overstated. With a victory, Notre Dame will be on track to earn a $13 million payout by winning out and earning a berth in a BCS game, perhaps the Fiesta Bowl. Tennessee, which has lost three in a row, is looking to salvage its season and make a bowl game. The Volunteers' offense should get a boost by facing a so-so Notre Dame secondary. But it remains to be seen if Tennessee -- or anyone -- can slow quarterback Brady Quinn. Notre Dame Coach Charlie Weis had two weeks to prepare, and you know how that usually turns out.
 California at  Oregon
3:30 p.m., pay-per-view
The Golden Bears' remaining regular season schedule is difficult, with road games against Oregon and Stanford and a home date with Southern California. Cal can win today, however, because Oregon will be playing without one of the better quarterbacks in the nation, Kellen Clemens, who is lost for the year because of a fractured ankle. Sophomore Dennis Dixon is under center, having attempted only 20 pass attempts this season. Oregon's running game has struggled as well, so the Ducks are in trouble. Oregon allowed its most recent opponent, Arizona, to rack up 411 total yards, so Cal could have a field day in Eugene.
 UCLA at Arizona
Admit it: You'll tune in for the fourth quarter, right? Consider this run by the Bruins: In four of their past five games, they have made double-digit comebacks in the fourth quarter. Dramatic? Yes. A national title contender? That remains to be seen. UCLA gives up 27.4 points and 430.1 yards per game. What's more, opponents average 5.1 yards per carry against the Bruins, so imagine when USC running back Reggie Bush lines up against UCLA at the L.A. Coliseum on Dec. 3. That's down the line, though. UCLA has more than enough to outscore an Arizona team that averages only three yards per carry.
 Texas at Baylor
12:30 p.m., Comcast SportsNet
This game can be summed up in three words: margin of victory. The computers used in the BCS formula don't care about winning margin, but the voters in the two human polls can't help but consider it. The Longhorns struggled last week, falling behind lowly Oklahoma State by 19 points before making a ferocious rally. If Texas struggles again against inferior competition and Virginia Tech pounds Miami, more voters could jump ship on Texas and choose the Hokies as the nation's second-best team. Regardless, Tech's numbers in the computers will improve this week because of the strength of schedule component.
