What about Illinois then? Three losses, Oregon, Penn State, and Minny at the end of the game. Would they then have a complaint?
Exactly - there is always going to be some "next team" that has as much of an argument to being included as the last team(s) in and is complaining about not being included. There's literally no way to avoid that. Bama, Miami-FL, Ole Miss, etc had their shot and failed by losing too many games. It wasn't like they were excluded by something outside of their control - don't look inept against a bad Oklahoma team and Bama would have made it in.
I don't see anything that happened this year that suggests that something "needs" to change. The good teams that have legit shots at the title all made it in (and are still playing).
