No G5 team will ever make it into the 4 team playoff unless the schedule Alabama, Clemson, Florida State, and Ohio state out of conference which is impossible and beats the all convincingly plus wins all the conference games by 10+ points. 8 teams would be the best and fairest way with each p5 conference sending their champion along with the g5 champion and 2 at large. The other option which I believe will happen is to organize all schools into 8 conferences and each conference sends their champion.
