All 4 P4 play 8 game conference schedule.
Each team plays one out of conference game with each of the other three P4. Every team rotates two home / one away every other year.
The other game can be a G5 or FCS game at the school’s own discretion.
With that data, the committee would have a better idea of the relative strength of each conference. It would also make teams prove it against other teams of similar caliber. It would force more road games for teams that have been playing 8 home and 4 away.
I know that money and power will never let this happen but it would help a lot
