On Saturday November 5th, the Tigers and Tide will meet in Tuscaloosa, effectively ending one team's national title hopes.
However, if there are two things we've learned over the years, it's that the BCS doesn't always make sense and the SEC holds a lot of weight.
Here are four scenarios that would allow these two SEC rivals to meet again in January for the Coaches Trophy.
If the loser of the 'Bama-LSU game runs the table after their meeting and the winner falls in the SEC championship game, we'll be left with two very good one-loss teams from the Southeastern Conference.
Every season, pundits debate whether or not a one-loss SEC team warrants consideration for the title game over undefeated teams from supposed "lesser" conferences.
It's not that far-fetched to believe that it'll happen one of these years.
If the Oklahomas, Wisconsins and Stanfords of the world fall, don't be surprised to see the previous scenario play out.
Undefeated or not, Boise State could be left on the outside looking in come January if there are a handful of one-loss teams from the AQ conferences looking for a place to play at season's end.
Big East notwithstanding, the ACC is viewed as the weakest of all the AQ conferences.
Given past performances from ACC teams in bowl games and traditional voter preferences, it will be tough for the Tigers to garner more respect than most teams at the top.
A 13-0 Clemson squad would be hard to pass up for any 12-1 team, but stranger things have happened.
There might be a logjam atop college football right now, but it's only mid-October.
We have a long way to go and a lot of games to play before this year's powerhouses finish the season unbeaten.
If teams start to falter along the way, Alabama and LSU could truly emerge as the two best teams in the nation, earning them a rematch in New Orleans.
