A would be OK, but it will never happen.
B would be a horror show, and there is no way Duke, Cal and Stanford stick around for those additions. BC and Wake would tag along with the prestige academic schools.
C is the same as B in practice. Unlikely that hodge podge would be worth joining.
One of the things that people don't get is that the rules for what constitute a conference are gone at this point. The minimum number of sports and the rest no longer apply because there is no way they would survive a court challenge. Those are much more anti-competitive than the rules around the player eligibility that keep losing in court. There are 4 scenarios that I think are realistic which wouldn't be terrible for UConn:
1) Football breaks off - I think this is realistic. If it happens, we are in a good place and will have some options as conferences are formed purely for football and basketball and other sports can be aligned in different conferences.
2) Big East/ACC merger - The ACC needs more and better content and the Big East pays for itself because it already has a TV contract.
3) The Prestige Schools break off - Stanford, Cal, Northwestern, Vanderbilt, Duke, Rice, BC, Wake split, maybe add a few other prestige schools (U of Chicago may want to be part of this) and form a D1 Ivy. Those schools get nothing out of being in major conferences, they could get a decent TV deal on their own, and they don't want the stigma of association with some of the wild west antics of state schools that are making a mockery of "student athlete". The alumni of those schools look down on the state schools they are currently affiliated with, and those same alumni would LOVE this league. There would also be enormous pressure by Notre Dame to join this league by its actual alumni (not internet fans). This scenario enrages several of the posters on this board. Good.
4) Schools drop out of competition. They may not officially drop out of D1, but they will downshift to something else. Many of these schools have huge financial problems, and they do not want to compete with Texas or Ohio State and their $100 million payrolls. I don't know what this will look like or which schools it will be, but I think this is likely to happen.
Those scenarios could result in a soft landing for UConn football. Any other scenario probably results in failure of UConn athletics. I think the latter is a very real possibility, so enjoy each season while we have them.
