I have been pushing for a 16 team playoff all inclusive of all 10 Div. 1 conferences for 20+ years but don't see it ever happening as long as the P5 schools have the leverage. In my opinion, there has NEVER been a true national champion in Div. 1 football because the teams that have been picked to play in the national championship game has ALWAYS been subjective. If it can be done in every other NCAA sport (basketball, baseball, softball, Div II and III football, tiddly winks...), then it could be done in Div. I. But this will never happen as long as the P5 schools have the NCAA wrapped around their ....
I love #4. I think get rid of all bowl games except for the 15 bowl games that would host the playoffs.
#1 is also a great thought. Standardized payment across the board, P5 to G5. I like #9 also, but will never happen because the P5's love to hoard players, though the transfer portal is making a difference in this.
Great thoughts, some of which I had thought of.
