My question is why not keep the existing/or modified BCS formula and go to 4 teams? I agree with most that the SEC chances getting 2 teams under the new format are slim to none even if they are deserving, and you can bet the loser of the SECCG is cooked. With all the anti-SEC sentiment nationally we will get screwed. An 8 team playoff would diminsish that concern but who knows if that will happen and in my opinion is too much because teams that play a conference championship will wind up with 16 games. Can you imagine the injury situation and/or general fatique by that point in time?
Because their very reason for being is to insure that there will NEVER EVER be another All SEC NCG. To do what you are suggesting, would, in most years, insure that there would be another.
