re: It's Oregon Vs LSU......if.......

if it comes down to an undefeated LSU and a 1 loss AL, ORE and OKLA, then the voters will probably look at it this way...

Did the team win their conference?
Oregon - Yes
Oklahoma - Yes
Alabama - No

Did the team have a key game in November against a highly ranked opponent with the conference on the line? What was the outcome?
Oregon - Won (stanford)
Oklahoma - Won (ok state)
Alabama - Lost (lsu)

Alabama's only real argument is a bunch of people think they're one of the top 2 teams. But the point of the BCS is to determine a champion on the field, not match up who everyone thinks are the best 2 teams and give the winner a trophy.
