The B1G makes no sense for Carolina. I don't think the ACC is going anywhere, but it the wildly unlikely hypothetical, I think that UNC goes to the SEC. We biased northerner like to pick on the SEC, but there is nothing wrong with the academic profile at Georgia, Florida, Alabama (yes, Alabama), Texas A&M and certainly Vandy is superb. Missouri and Tennessee are certainly no worse than the likes of NC State and are better than Louisville. So the potential SEC EAST division that UNC would join would have a perfectly acceptable academic profile.
Just curious...you say the B1G makes no sense for Carolina. Ok, but, would it for Virginia, and, why them, but, not UNC? Because...and its solely my own opinion, we are more connected to UVA than anybody else within the ACC. Including Duke, and, NCSU.
You are very correct about Vandy, UF, UGA, and TAMU being excellent academic schools in the SEC. Alabama is an up-and-comer, too.
Now the real world is that both Carolinas are growing, along with Florida and Georgia. The upper midwest. Delany mentioned this several times, he wanted into the ACC footprint in part because it has better long term demographics. The ACC schools know this and should know that if they can hold together, they are in a great position, better than most of the other conferences really.
