Auburn vs Alabama rematch
It could happen. But a lot would have to happen for it to happen.
Alabama loses to Auburn by one point or something. Another GOTC type of finish. Drops to #5 or #6 in the polls.
Absolutely has to happen:
FSU loses to Florida or Duke (hahahaha).
Ohio State loses to Michigan State.
Auburn beats Missouri in the SECCG.
Baylor loses to Oklahoma State.
Oklahoma State loses to Oklahoma
Oregon loses the Pac 12 championship.
Would probably need to happen:
Clemson loses to USCe.
Actually what would be more fricked up would Missouri losing to Ole Miss or A&M and then beating Auburn in the SECCG. Then enough teams in the top ten lose to move Alabama back into the BCSCG against an undefeated FSU.
Don't say it can't happen, but 2011 and 2012 did happen!
