Same thing was said about conference expansion, NIL and pay for play at one time. Think about relegation for a moment. It doesn’t have to be for anything except for CFB. So an example of conference partners would look like this:
SEC - Sun Belt
B1G - MAC
ACC - CUSA
B12 - AAC
P12 - MW
Its made for TV late season matchups that would create sold out lower tier bowls as for example SEC #16 Vandy & ACC #16 UVA are being relegated and the top 2 Sun Belt, MAC etc are playing to be promoted into the P5 conference which will provide all the additional $$$ and opportunities to remain. While the current P5 programs (Vandy, UVA, etc) will have reevaluate the commitment to get back into the P5. This will eventually show who really wants to be a competitive program or not as time goes on. It will show who really has the backing of the school itself.
Keep in mind, the P2 & MW have supposedly already been in talks to do this.
