It was a fumble return. But yeah, a loss by LSU would be an interesting plot twist
#1 LSU, #2 Alabama and #3 Arkansas are all in the Southeastern Conference. Not only that, but they are all in the SEC West -- which means only one of these three will be able to play in the SEC championship game.
In the SEC West, the BCS standings have 9-2 South Carolina (#13) ranked over 9-2 Georgia (#14) because SC beat Georgia earlier in the season. But Georgia is in first place in the SEC West because they are 6-1 in the conference while SC is 5-2, so Georgia will face one of the top three teams from the SEC East in the conference championship game. If Georgia wins the SEC championship game, then there's a good chance that the BCS title game would involve a matchup between two SEC teams -- neither of which was able to win its own conference championship!
As a side note . . . When you look at these rankings and these potential scenarios, is there any doubt in anyone's mind that the SEC is the most dominant conference in college football?
