One other thing....fair or unfair, neither BSU nor TCU right now have a victory over a team that's currently in the top 25. (Both played Oregon State, and BSU played V-Tech, and both the Beavers/Hokies were ranked at the time....but both are currently unranked).
It may not seem fair, but right now, Oklahoma and Oregon have victories over teams that are currently ranked (Florida State and Stanford, respectively), and BSU/TCU don't.
