Let's just all join up (I'm at about a 5 right now, FYI)
First scenario: Pick 64 of the Power 5's, make it 4 - 16 team conferences w/ 4 - 4 team divisions each. Play the other 3 in your division every year, and one other division (switches off) each year, for 7 confy games. Require 2 other power 5 (or 4, whatever they'll be called) games in the non-con, go back to an 11 game reggie season, expand the playoff to 8.
Second scenario: Pick 72 schools, make 6 - 12 team conferences w/ 2 - 6 team divisions. Play the other 5 in your division and rotate 3 from the other division. Require 1 other power 5 (or 6, whatever they'll call it) game in the non-con, go back to 11 game reggie season, expand playoff to 8.
You're welcome sports fans.
(These would probably never work, or maybe it would..I mean, it could, and would be fun, I think, maybe. Feel free to make your own adjustments to the landscape, or don't.)
