The AP top 8 will definately guarantee the top 2 or even the very top 4 getting in with or without bias of a league champ thing which can create a whole new can of worms to createadditional bias... therefor 2 sets of bias over a simple 1 through 8 AP invite. The only bias effect of an AP 8 formula would be the 'seating' by the bias in ranking and that would occur in any formula... yet the only formula that promises the best 4 to 6 teams ... therefore again, the top 1 and 2 teams. But if it has to be only 4 teams... then AP top 4 in fairness to all teams and conferences... but don't believe, for a moment, the Godon Gee types and many on this forum want anything to do with that sort of fair play scenario recipe or it would not have been brought up in the 1st place... if there wasn't an angle of eliti$m, with some sort of self advantage involved.
We'll simply have to disagree. Oh well, neither of us is in a decision making spot.
I think there is less bias by winning your conference on the field than by relying on voters.
PS. How do you know a conference ranked #5 is worse than a conference ranked #3 if they only play one or two games the entire season vs each other? Also why is winning your conference not good enough to count as a first round of a playoff?
