We have probably seen the seismic upset of the week in college football, thanks to Iowa State's 37-31 overtime win over No. 2 Oklahoma State on Friday night. But there are still more games featuring ranked teams that could produce pivotal results in Week 12 that might shake up the BCS rankings even further.
Here's what's at stake in Week 12.
No. 1 LSU vs. Mississippi, 7:00 p.m.
If LSU wins: The Tigers keep all their national title and undefeated season hopes alive. And only Arkansas remains between LSU and a spotless regular season.
If Mississippi wins: The Rebels will have pulled the biggest upset in college football this year ... and LSU might not fall out of the No. 1 spot. If the Tigers lose, they will be a one-loss team, but one with wins over the presumed No. 2 and No. 3 teams in the nation. Could poll voters keep LSU at No. 1 even with that major upset because of its strength of schedule and impressive wins? Houston Nutt might have enough magic left to make that hypothetical a reality.
No. 3 Alabama vs. Georgia Southern, 2:00 p.m.
If Alabama wins: Welcome back to the national title conversation, Crimson Tide. Alabama will likely move up to No. 2 in every poll with a victory over FCS Georgia Southern, and would be in line for a rematch with LSU in the BCS National Championship Game.
If Georgia Southern wins: I give up on writing about college football, because writing about the weather on Neptune would be easier and make more sense.
No. 4 Oregon vs. USC, 8:00 p.m.
If Oregon wins: Depending on the margin, the Ducks might erode some of Alabama's lead on them in the BCS rankings. That will have to come almost entirely from the human polls, because the computer rankings hate the Pac-12, but a 35-point win over the Trojans, for example, might make a few voters reconsider blindly moving Alabama and Oregon up in that order after Oklahoma State's loss.
If USC wins: Uh, well, Oregon can play in the Rose Bowl. And Lane Kiffin has a massive win to hang his hat on entering his third season in Los Angeles.
No. 5 Oklahoma vs. No. 22 Baylor, 8:00 p.m.
If Oklahoma wins: The Sooners' unlikely national title candidacy may be back in play. If Oklahoma can run the table, its strength of schedule and hypothetical win over Oklahoma State may give it a fuller list of credentials than Alabama or Oregon, and could start one of the nuttiest debates about BCS title contenders ever.
If Baylor wins: Bye, Oklahoma. And bye, Oklahoma State, too: the Cowboys' outside chance of a trip to the head of the line of one-loss teams relies on a win over the Sooners, and only a win over a one-loss version of them would be a suitably large boost. Oh, and that Robert Griffin III guy might yet have a shot at the 2011 Heisman Trophy.
No. 14 Georgia vs. Kentucky, 12:21 p.m.
If Georgia wins: The Bulldogs win the SEC East, and provide the SEC West winner, likely LSU, with a final top-15 opponent on the road to the BCS title game.
If Kentucky wins: South Carolina, which has been an underwhelming outfit since the loss of Marcus Lattimore to injury, will be the SEC East's representative in Atlanta. And the Gamecocks will lose a second straight SEC Championship Game. (Note: Kentucky pulling the upset will not happen; I'm pretty sure that South Carolina loss would.)
