Here's a quick point to consider - not because I want a rematch, but because I think this needs clarification. The idea of a rematch by itself doesn't crap all over the regular season - only because there is now a deserving team that can put up a solid argument for the title game. Had Florida lost, not rematching would have been the scenario that rendered the regular season meaningless - because then, you lose twice, you still make it, and how is that fair? Of course, the SEC would then scream bloody murder that they're penalized for having a championship game, but that's their problem; they were the ones who wanted the $$$ from the game in the first place. So, it's not that the BCS is troublesome because it could potentially provide a rematch. It's that we basically now have #1, #2A, and #2B.
And rationalizing that Florida lost on the road in a game that came down to a couple of plays really doesn't help Florida. First of all, so did Michigan. Second, Arkansas went to the same stadium, played the same team, and wiped the field with them. Florida should have won that game if they want to be considered the clear-cut choice to oppose Ohio State. It's not the BCS's fault that Florida doesn't have a rock-solid case for playing in the game.
