So suppose we win out (theoretically... Don't jump down my throat)...
Next suppose Kansas State wins out and meaning Iowa State loses to Kansas State.
In these circumstances I think we would have a rematch in the big 12 championship game.
At that point in the season, I don't think it would matter who won or lost in the game, I think both teams would probably get into the playoffs. If things worked out just right there, then it's possible to play them a third time.
