I get that Gonzo is an Iowa fan, and the Big 10 might just be the best academic conference outside of the Ivy League, but I've never understood ISU fans calling the SEC a "cesspool academic conference." While I consider ISU to be a very good academic college, when it's the second or third best college in the Big 12 academically, it's essentially the pot calling the kettle black. For instance, Taco Tech, K-State, and West Virginia are probably as bad if not worse than anything the SEC has to offer.
My point was that I think, academically, UNC would rather run with schools like Michigan, Northwestern, Virginia (if it happens), Wisconsin, Illinois, Penn St. I know realignment is about TV markets and athletic dollars, but academics and academic reputation is a big-time concern to a lot of alums and donors. Maybe 'cesspool' is a bit strong, but the SEC isn't close and UNC just would seem like a strange fit.
