How about Texas and Oklahoma join the West, and UNC and UVA (or WVA?) join the East?
Personally I've always wished we could trade Vanderbilt for UNC.
THE University of North Carolina belongs in the SEC with all the other charter public universities of the South, to wit:
THE University of South Carolina
THE University of Georgia
THE University of Florida
THE University of Kentucky
THE University of Tennessee
THE University of Alabama
THE University of Missouri
THE University of Mississippi
THE University of Arkansas
THE Louisiana State University (of course Louisiana always has to be different but you get the point)
