The problem regarding ACC expansion is that most schools will not view it as an upgrade worth pursuing. I could see West VA and Cincy, but I have a hard time thinking of another school that would want to join us if expansion continues. The other Big 12 schools are closer in footprint to remnant schools of the PAC like Arizona, Ariz St., and Utah. Perhaps as TooTall mentioned, a merger is needed to survive.
I saw on one forum (if it was here, I apologize for repeating) that if the ND to the Big 10 domino falls, it may open the door for ACC schools to argue that the media/tv deal is null and void due to the change in scheduling. If that is the case, Clemson, Miami, FSU, UNC, and VT are free to do as they please if the mega conferences come knocking.
A lot of people are knocking the "nerd conference" idea. Whether we like it or not, Tech is going to have a hard time trading up if the ACC fails. Our traditional ACC rivals either don't consider us a primary rival (VT, Duke) or don't need us to sweeten their deal with another conference (Clemson). We need to hope the ACC stays in place and expands, otherwise we lose the opportunity to improve our lot.
