Apart from Colorado State's out of conference success, I agree with your comparison of the listed teams to the MWC.
What you're suggesting is similar to an idea I was pushing on the Sunbelt Realignment forum. It's my feeling that sooner or later C-USA will have to split or totally disintegrate. If the BE is only interested in one of these teams (Louisville I'd guess), I'd suggest including Memphis and possibly UAB (if they stay afloat) in your conference, then you'd have 12 members (if you wanted that many), and could split into Delta and Plains divisions. You'd probably have Arkansas St. and North Texas as options as well.
As far as starting a thread on which of these teams woudl be snapped up by the BE and/or ACC, I think you can just go to the main board and click start a new thread. Apologies to the administrator if this is not correct.
I think the BE, depending on what's going on with Notre Dame, would take a serious look at Louisville, ECU, So. Miss, and maybe Army. Army would just be for the potential benefits of having both Army and Navy in the same conference (I doubt they'd go for it). Louisville seems like th eonly solid fit for the BE which would conribute in both sports and which would not generate any major objections. So Miss is probably the only option among the deep south members. A bit of a stretch regionally, but it'd be interesting to see how they'd fare in a major conference where they face Miami every year. Recruiting might surpass what's going on at Ole Miss right now (which is scary). I think many of the former C-USA teams in the southern region cold potentially find a home in the Big 12, if there were room, or, if the Big 12 ever breaks apart, in a reformed SWC.
TCU is just too much of a geographic stretch for the BE, but if they keep laying football at this level, the Big 12 will have to be interested. USF will probably be a major success in C-USA, but I doubt that Miami would allow then into the BE, too much of a recruiting threat. They'd be an excellent team to have in a new non-BCS conference of southern teams. I don't know if they could find a home anywhere else, unless FSU and the pro football ACC schools gain control of decision-making in the ACC and they decide to add a Florida team (no doubt to kill Miami in recruiting). I already think of Marshall as a C-USA team, though that may never happen. At any rate, if they do join, I think they'd lobby to move up into the ACC or BE. They'd have abetter shot at the BE, because the only West Va (as far as I know) would have any major objection to them joining. But that might be enough to keep them out. There's no way the ACC would let them in, WAY too many academic questions and the school is all about football.
