Boise State the only undefeated team?

Nobody thought any of this was going to turn out this way. Ohio State still has time, but I guess they don't look as dominant as everyone thought. Nobody thought Michigan would loose, I don't wanna go down the whole list of Nobody thoughts, but nobody thought Boise State would win their bowl game, but now it looks like they will be the only undefeated team in Division 1-A. What should this mean?????
