Neither CyFan nor CyTwins actually think Rudock is better than Beathard. I'm sure they do believe Michigan is better than Iowa, which is something that most computer models would disagree with.
Obviously Iowa has to go 13-0 to make the playoff. Their schedule over the course of the season is very weak. However, a one loss Iowa team is not getting in to the playoff over a one loss traditional power (Alabama, Florida, Ohio State, Florida State, Notre Dame, etc.) no matter what their schedule looks like; that's just the way things are. The only issue that Iowa fans have right now is there is no discernible reason for Iowa to be ranked behind teams like Florida State, Stanford, or Notre Dame based on each team's resume at this point in the season. Hell, Iowa just passed Oklahoma State in the rankings this week when Oklahoma State's schedule to this point is far worse than Iowa's.
