The teams and conferences that made it in during the first couple of years are obviously more likely to just keep doing so. Every year it just gets worse. And it won't improve if we let in three SEC teams; that will just happen every year and block everyone else from the CFP, and from getting top recruits, leading to a worsening of our current vicious circle.

I'm not sure what the answer is, but it has to be some way to reduce the effect of the same teams from getting in every year.

An 8 team playoff with only conference champions might do it.

Or a 16 team playoff with no more than the top 2 teams per conference might do it. Seed the two same conference teams against each other in either the first or second round. Let Alabama and Florida or Georgia host numbers 16 and 15 in the first round, then play each other to get into the final four. Sometimes Alabama will lose that one and college football will be better off because of it.
