I would also suggest that any team that doesn't have to play in a conference championship should be ineligible to win the national title. Ohio State won the Big Ten by winning out in the regular season, while some teams (like Florida) then had to go on and prove themselves one more time against a very difficult (especially in the SEC) opponent in a conference championship game.
True. I would have liked to have seen Ohio State play Wisconsin.
That's the decision by the conference. And Notre Dame isn't even in a conference, so if they could actually live up to their hype it would be troublesome for them too.
The BCS isn't around to make things fair, it's to try to preserve the status quo of powerhouse teams.
