I like your thinking. This would help to get to a true, FBS playoff, whereby solely conference winners playoff. One of the remaining conundrums is what sense does it make for a CFP, conference champion to play a same-conference team they’ve already beat in earning their conference championship, in the CFP (i.e. Oregon already beat fOSU & PSU; further they already beat Boise as well)?
If they could get to a true playoff, a tournament of champions, it would be so much more enjoyable, and so would the remaining bowl games, outside of the tournament of champions. I find this year’s invitational tournament boring so far but am looking forward to some bowl games.
