SEC/BIG would both want UNC, no question. Brand, "academics" (theirs are .... questionable due to fraud but that's another thread) new footprint/market for both, make no mistake UNC and their brand is highly desirable.
Miami IMO would be a bigger get for the SEC than the BIG due to the SEC's lack of bigger markets compared to the BIG but I could see the BIG wanting them too for that same reason and to get into Florida to go with California.
Clemson/FSU are desirable, UVA too to a lesser extent.
WE might see a combo move by both the SEC and BIG to nab ND, Miami, Clemson, FSU, UVA, UNC, DUKE and maybe..GT? and destroy the ACC and its GOR with one move.
