The weekend if LSU beats Alabama then there will be some shit in the city. With the rest of LSU's schedule they will more than likely play Georgia in the SEC championship and lead to some big questions as far as the National Championship is concerned.
Really though I can't wait until the 4 team playoffs.
Controversy would still come in the form of having 3 undefeated teams at 1-3, then probably 4 1-loss teams vying for the 4th playoff spot.
