What are you talking about? There is no reshuffling or re-seeding after rounds. It is a set bracket with 12 teams, period. If anything with the current system they SHOULD re-seed after each round but they do not.
Ole Miss nor Bama had any argument to be included , as soon as you have 3 losses you lose any argument to be included, as at that point it is not just about wins or quality wins but also about your losses (Ole Miss losing to Kentucky, Bama losing to Vandy and OU).
12 teams is perfect, and I am even OK with the 5 highest ranked champions being included. HOWEVER, they need to drop the 4 highest rated conference champions receiving a top 4 seed (and getting a bye). They are trying to implement an NFL model, but in the NFL all teams play each other or in the same league. Even then there is a strong argument that just because you are division winner you should not be guaranteed a home playoff game (one of 14 win Detroit or Minn. Is going to have to play on the road to a team that won 4 or 5 less games than they did)
It is fine to include ASU and Boise and Clemson in the 12 team field as conference champions, but they should have been seeded 9 - 12. It is ludicrous that ASU and Boise got top 4 seeds. It also then has the problem of some lower seeds have an easier path than higher seeds, and also knocks out a higher seed in the QUARTER finals instead of the semi-finals. The 12 team field just needs to be set based on the final CFP rankings with any conference champs outside the top 12 supplanting teams ranked 10-12.
Final CFP rankings this year:
1 Oregon
2 UGA
3 Cow
4 PSU
5 Notre Dame
6 Ohio State
7 UT
8 Indiana
9 Boise State
10 SMU
11 Alabama
12 ASU
……
16 Clemson
So that should have resulted in ASU being # 11 and Clemson being # 12. With the current system ASU got moved all the way up to #4 and #9 Boise being moved all the way up to #3!!!!
FWIW I do think they will make this change in the off-season. Will still guarantee the 5 highest rated conference champions are included in the 12 team field, but the top 4 seeds will be based solely on the final CFP ranking and any conference champs finishing outside the top 12 will be seeded 11-12 depending on how many there are.
