I'm not sure I agree with anyone about UNCand Virginia to the Big 10. Some things are a bridge too far, and that seems like one of them. Culturally, and in every other way, those schools are just not good fits any more than a northeastern urban Catholic Boston College was a good fit in the southern ACC. You just need to walk onto those campuses compared with Michigan or Ohio state or Iowa and you see and feel a totally different vibe. And basketball is clear ACC king. Not so in the Big. Could someone do something that dumb for money? Sure. But I don't really think UNC or UVA would tend to go that route. Maryland is a different sort of animal, probably more north than south and it could likely make such a move but unless things look pretty desperate i wouldn't look for UNC or UVA to do it. UVA's other problem is VaTech. although UVA is the flagship, Tech is the largest public university in the state and no governor or legislature is going to let VaTech be left high and dry, even for the B-10. Not happening, so unless and until VPI has a home, UVA ain't going anywhere.
The funny thing to me would be if the ACC spiraled out of control and Pitt Syracuse BC and Maryland all ended up in a new league with UCONN, Rutgers Louisville, Cincinnatti, and south florida...
