Speaking from an SEC fan's point of view, if they were to expand to 14 or had to replace a departed Arkansas, I'm not sure it's a done deal that they raid the Big East, ie. WV and Louisville.
It wouldn't shock me if they fought expansion fire with fire and go after the ACC.
As an SEC fan (Georgia in particular), I'd love to have NC State and/or Florida State in the fold.
I think WV is just too far out of the footprint (you're a stones throw from Pennsylvania! That's up there).
And no disrespect to Louisville, your basketball and football are solid, but we already have a presence in the Kentucky market, where we have no part of other southern markets such as North Carolina, Virginia, and Texas for example.
At this point, I would bet that Florida State fans would be beside themselves with gitty glee to get out of the new Monster Eastern Seaboard ACC and come to the southern centric SEC. Clemson too, for that matter.
I'm not saying it's not possible that UofL, WV, or even Memphis wouldn't make it in an expansion scenerio, I just think that the SEC would exhaust wooing the ACC southern schools first and I feel like NCSt and FSU are the most attainable of the desired.
