One solution to the PAC situation would be to let the Four Corners leave (or push them out) and then add four G5s that won't complain about unequal distribution.
PAC North schools + SDSU, Colorado State is relatively easy. Those add markets and good-enough academics. Assuming they want to go to 10, then it gets tricky. Boise has the media value but not the academic clout. Fresno might have some CA state politics help. Nevada, Wyoming, New Mexico, and Hawaii are state flagships and easier for the PAC to stomach. SMU could plant a flag in Texas, has a decent athletics brand, and is a US News Top 100 school.
My guess is that they could figure out how to raid the MWC/AAC and make it work.
End result of this would be FOX gets its late night games via the B1G/B12, Disney keeps PAC after Dark and the remaining valuable PAC brands, and the Oregon/Washington/Stanford group might end up making more money individiually than anyone in the Big 12 due to unequal revenue distribution.
