In college football's current "playoff" system, only two teams truly qualify each year. And even elite programs such as Florida and Oklahoma need to catch a break or two to find their way to the BCS Championship Game. So, before banking on a rematch of last year's title bout, remember this: Only four of the 11 BCS title games to date have featured a matchup of two undefeated contenders. That means someone is likely to stumble, and it's a tough road back to the top when that happens.
