The thing with sports is that there are NO ABSOLUTES. ANY team can win on any given day.
Look at Iowa. They beat Miami(OH) who was otherwise undefeated. They beat Michigan who were the Big 10 champs and went on to play in the number 2 BCS bowl. They beat Florida who in turn deafeated LSU who is contending for a national title.
So long as you have human players and human error, you will never have absolutes. Arguing otherwise is pointless.
EDIT - the only way you will EVER have a undisputed champion(and even that can be disputed depending on invites) is to have a playoff system like the NCAA basketball.
