top 12 automatically gets in. If a P5 conference champ doesn't crack the top 12, no auto-bid for that conference. If the MWC and the AAC both have teams in the 9-12 range, they both get in. Fill out any remaining spots with the highest-rated non-conference champs. If you have more than 8 conference champs in the top 12, take the top 8 of those champs (not that this would ever happen). This gives every team in every conference a reasonable chance to get in, and if you're a conference champ that can't crack the top 12 then you don't really deserve to be in an 8-team playoff anyway.
