If Arkansas can pass by LSU on Friday... they should move up to number 1 cause LSU has proven to be the definitive number 1 team in the country... not Alabama. LSU beat Bama on their own turf, stopped Oregon on neutral ground, and defeated West Virginia. LSU has the body work to stay at number 2... IF they were to lose to Arkansas. But then it would also depend on the beating. If its close then LSU stays at 2. If its moe than 14 points then they should move to 3... depending on how Bama does against Auburn.
But lets keep it simple... Arkansas wins by 10, they move up to 1, LSU at 2, Alabama at 3. Arkansas plays in the SEC championship game since they are now leading the SEC west since LSU topped Bama which was topped by Arkansas. They beat UGA and march on to the BCS national title game against LSU. Bama is gonna wind up in the Sugar bowl.
If LSU drops to 3... its gonna be crazy.
So pretty much... the BCS stability, whats left of it, all depends on Arkansas on Friday cause if LSU happens to lose the SEC Championship I think they will only fall to 2... and would still be in the national title game. And all Alabama has to do to control their destiny is beat my team. We may have an all SEC West national title game.
