Give LSU head coach Les Miles a lot of credit. He's never afraid to make the tough call on fourth down.
Trailing 14-13 in the middle of the fourth quarter against Alabama, Miles could've opted for a field goal to take the lead. Instead, he called for a reverse on 4th-and-1 from the Alabama 26. DeAngelo Peterson ran 23 yards and Stevan Ridley scored three plays later to put LSU up 19-14. The Tigers added the two-point conversion. LSU tacked on a field goal and then held on as Alabama got a late touchdown.
That call was key in a 24-21 win over the Crimson Tide, eliminating Alabama from any chance to make the BCS national title game as a one-loss team. Alabama will also likely not make a BCS bowl, especially if Auburn finishes undefeated and LSU finishes with just one loss.
Auburn controls the SEC West. Auburn would need to lose twice to put LSU in position to win the SEC West. Auburn has already beaten LSU, 24-17. Alabama needs LSU to lose twice, have Georgia beat Auburn and then beat Auburn in the Iron Bowl to win the SEC West.
If Auburn and LSU win out, Auburn will win the SEC West, play in the conference title game and potentially in the BCS national title game. LSU, at the very least, has positioned itself for a BCS bowl game, perhaps the Sugar Bowl.
