Option 4.5
Stick with the PAC and add Kansas from the B12 and Rice from the CUSA. Both are AAU schools. As well, Rice gets the conference into Texas and specifically into the Houston market (top 10).
CBS is undoubtedly scrambling to put something together with the PAC. If you recall, they lost out on the new SEC contract and indicated they were looking at working with other conference(s). If they can pull it off, maybe they keep UW and OR in place… Losing the LA market is a huge gut punch, but even then, the PAC minus LA is still more interesting than the B12, loaded with G5 garbage.
