the problem will be when you have some 15th+ or higher conf champ that gets in over a top 11/12 team that maybe lost a conf title game to a UGA or something.
it will provide some drama for teams that are in that 11-14 range most years to see where the fall, and who wins what conf title games, so i guess that's good, until it's your team that's sitting there at 11 and Memphis gets in because they upset Baylor in the Big 12 title game......
but honestly, i don't think that will be an every year thing...i'd say most years the auto bid conf winners probably will be solidly in the top 12, and your big boys that are in the top 10-12, but didn't win the conf, probably get in anyway. could be interesting for say a #10 team that plays a top 4 team in a conf title and loses....do they get punished for losing a title game that had they not played in, would have put them in the play off?
like said, drama. so err'body wins, i guess.
