With over 100 teams, it's hard to design a football playoff system that doesn't leave some deserving team out.
This system is highly flawed, but the NCAA cannot have a 32 or even 16 team playoff structure. If they think they can do 6, then they might as well do 8.
Of course, once you go to 8th, the 9th and 10th teams will be screaming about how unfair the new system is, and many times they will be right.
So much of the way these teams are chosen are based on opinion- some straight from the pre-season rankings that are based on nothing but opinion. Teams are also chosen on the basis of the perception of how strong their conference is and specific teams' schedule strengths. It's easy to imagine that the SEC is not always equally strong, but they are always assumed to be the far away strongest conference. (I'm not saying it isn't always the best, but how can we really ever know, for sure?)
These ideas they use to select the 4 teams is based on who they think are the best teams, now. They factor in injured players, the recency effect and almost always head-to-head tie breakers. In a warped way, this is how AL and Tex got in over the 13-0 FSU. AL beat #1 GA and won the strongest conference, so they have to get in. Texas has the same record as AL. so they have to get in. Did Texas really beat that many top teams? What about losses? They seem to count less.
A one loss team like Ohio St. lost its one game, on the road, to the current #1 team Michigan by a field goal. Once could argue they are the best 1 loss team.
FSU clearly played a lighter schedule, but no losses should outweigh what AL & TX did. Afterall, FSU did beat 3 ranked teams.
Georgia played a tough schedule, and ended up losing a close game to a top 4 team. Sorry, you lost your last game- you suck!
What makes Wash better than FSU? The apparent strength of the PAC-10, which I find doubtful. Are ORE, USC and AZ really all that better than Penn St, Missouri and other teams that looked tough, this year?
Anyway, had they chosen FSU, we'd be hearing AL or TEX bitching away, and rightfully so.
