I think that most of you guys have got it wrong.
The perfect number is 6 Teams for the CFB-Playoffs.
The Top-2 seeds get those seeds based on SoS or W-L record vs. the toughest schedule kinda like a CFB version of what basketball uses to give out #1 seeds for the NCAA tourney, it would be possible for those 2 teams to be from the same conference or the Top-2 seeds could be independents (BYU & ND) from no conference for example.
After the Top-2 seeds are chosen the next 2 seeds are chosen based on the Conference Champs of the next 2 toughest conferences, it could be the Champs of the numbers 1 & 2 conferences if the top-2 seeds are filled by Independents or they could be the Champs of the 3rd &4th toughest conferences if the first 2 seeds are populated by the champs of the Top-2 conferences or they could be filled by the champs of the 2nd and 3rd toughest conferences if the top-2 seeds came from the same conference, the same would happen if you had one independent team and one conf. champ as the top 2 seeds.
The last 2 seeds the 5th and 6th seeded teams would be at-large based on W-L record vs. the toughest schedule.
The ideology behind doing it this way is to give incentives for Conf. comissioners and ADs to increase the number of conference games to 9 or 10 conference games and to limit the numbers of crappy games scheduled vs. FCS teams.
If SoS factors heavily in everything associated with the new playoff system, then that will limit the Media lovefest with the SEC and it will give conferences like the ACC to schedule their way into the Nat'l discussion if they choose to do so.
If you guarantee conference champs slots in the new playoff system, then weak conferences have no incentive to increase the numbers of conf. games played and then the ADs will simply use the OOC games for scheduling cupcakes.
Under this system no more than 4 of the 6 playoff slots can go to Conference champs, so the ADs and conference commissioners will have to WORK at toughening up their schedule each yr, to give their programs a chance at the playoff system.
Under my proposed system going 11-1 vs. a weak schedule is not likely to get you a top-6 seed.
No automatic qualifiers, the 6 seeds go to the teams with the best W-L records vs. tough schedules.
With the current system IMO, there is too much of an incentive for schools to water down the schedule to try and get a top-4 seed, under my system even with 2 extra teams, there is an incentive to play better teams in the reg. season which is great for all CFB fans.
Teams that are serious about having a shot at the playoffs under my system won't have 4 cupcakes for their OoC games.
Once all the teams are chosen, the 1 and 2 teams get a bye and then the 3 seed plays the 6 seed and then the 4 seed plays the 5 seed, and then based on the winners of those games the #1 seed gets the highest seed and the #2 seed get the lowest seed left.
