We had to play Iowa, and Iowa had to play us. Hurts them. See how stupid that is? All we had to do was beat them and they wouldn't be undefeated. Same with 11 other schools. I just hate the argument, because it's predicated partly on preseason rankings and then if you beat the team in front of you - and conferences are so different and rarely play each other before bowl season.
I don't know what you're trying to argue. You said it yourself Oklahoma would blow out Iowa so if Iowa had our schedule they wouldn't be undefeated. Problem solved
