IOWA AT OHIO STATE
When: 3:30 p.m., ABC regional/ESPN
Broadcasters: Sean McDonough play-by-play, Matt Millen analyst
The line: Ohio State by 16.5
Why you should watch: Maybe some Ohio State fans were frustrated with the Buckeyes earlier this season, but - what do you know? - the Buckeyes can all but clinch a Big Ten title and a trip to the Rose Bowl by defeating a depleted Iowa squad. If anyone is keeping track, that would give coach Jim Tressel at least a share of five consecutive conference titles. After losing for the first time last week, Iowa is vulnerable. The Hawkeyes have had injury issues all season, and now have lost starting QB Ricky Stanzi for the rest of the regular season to an ankle injury. That means Iowa will have redshirt freshman James Vandenberg at quarterback and true freshman Brandon Wegher at tailback. Iowa's defense is tough, but so is Ohio State's. The Buckeyes have allowed an average of 183.0 total yards per game in the three games since they lost to Purdue. In that span, Ohio State has forced eight turnovers and held opponents to two offensive touchdowns.

MIAMI AT NORTH CAROLINA
When: 3:30 p.m., ABC regional/ESPN
Broadcasters: Bob Wischusen play-by-play, Bob Griese analyst
The line: Miami by 3.5
Why you should watch: Georgia Tech clinches a trip to the ACC championship game if it beats Duke on Saturday, but this game is important for bowl positioning. Miami is ranked 14th in the BCS this week, and a 10-2 finish will keep UM in the mix for a BCS at-large spot. North Carolina, meanwhile, can move into a more high-profile bowl if it wins its final three - against Miami, Boston College and North Carolina State. UNC coach Butch Davis is 2-0 against his former team. North Carolina's pass defense has been stingy all season, with the exception of a three-point loss to Florida State on Oct. 22.

STANFORD AT USC
When: 3:30 p.m., Fox Sports Net
Broadcasters: Barry Tompkins play-by-play, Petros Papadakis analyst
The line: USC by 11
Why you should watch: Stanford's 51-42 win over Oregon last week re-opened the Pac-10 race, meaning USC remains alive for its eighth consecutive Pac-10 title. Working in USC's favor is playing its last three opponents at home, plus Pete Carroll's 26-0 record in November. Stanford has no reason to be intimidated, having won in the Coliseum two seasons ago. Stanford RB Toby Gerhart is the nation's second-leading rusher, and redshirt freshman QB Andrew Luck has thrown for more yards, more touchdowns, fewer interceptions and more completions in fewer attempts than USC counterpart Matt Barkley. If Stanford can beat Oregon in a shootout, shouldn't the Cardinal be able to give USC trouble?

UTAH AT TCU
When: 7:30 p.m., CBS College Sports
Broadcasters: Tom Hart play-by-play, Aaron Taylor analyst
The line: TCU by 19.5
Why you should watch: This is the second game between ranked Mountain West teams this season - and the second that will be difficult to find for TV viewers. The Horned Frogs' 38-7 victory over BYU last month was carried on Versus. (TCU's non-conference win at Clemson in September wasn't televised at all.) Utah's only loss is by a touchdown at Oregon, but the Utes have reason to be cautious about this game. True freshman QB Jordan Wynn is making only his second career start and his first on the road. And that first start was against winless New Mexico. This is against undefeated TCU, a team that ranks in the top five nationally in total defense, scoring defense and pass defense.

NOTRE DAME AT PITTSBURGH
When: 8 p.m., ABC regional/ESPN GamePlan
Broadcasters: Brent Musburger play-by-play, Kirk Herbstreit analyst
The line: Pittsburgh by 7
Why you should watch: In 2005, Notre Dame and Pittsburgh hired alums who had won Super Bowls as coordinators but were first-time college coaches. These days, Pitt's pick of Dave Wannstedt is looking better than Notre Dame's of Charlie Weis. Notre Dame may be playing for Weis' job in the final three games, against Pitt, Connecticut and Stanford. This game won't affect the Big East race, but it could raise the national profile for Pitt and the conference. Pitt will be one of the best offensive teams Notre Dame has faced this season and certainly one of the most balanced. True freshman RB Dion Lewis is seventh in the nation in rushing, while senior QB Bill Stull is the fifth-most efficient passer in the nation. The game will feature some of the nation's best weapons in the passing game in Notre Dame's wide receiver duo of Michael Floyd and Golden Tate and the Pitt tandem of WR Jonathan Baldwin and TE Dorin Dickerson.
