LSU dropping to Arkansas wouldn't by itself mess anything up. The SEC West 3-way tiebreaker - thanks to Stewart Mandel, I know this - is head to head among the top 2 teams of the 3 in the BCS rankings. In short, since Arkansas and Bama would surely leap past LSU if Arkansas beat the Tigers, Bama would go to the SEC title game based on head to head with Arkansas. If Bama then won the SEC title, and Okla St didn't lose a game, they'd play the Cowboys. If not, Bama/Oregon would be a very interesting title game matchup. So if LSU loses once, two teams they beat play for the title? God there needs to be a playoff.
