Actually, on second thought, the challenge conference needs to be the WCC. They're back up to 10 now with Pacific.
The CAA really is in flux right now. I know that some combination of Old Dominion, Delaware, William & Mary, Towson, and James Madison have loosely talked about going to FBS, and going together in some form. Georgia St is already gone. We all heard about VCU and Mason and the A-10, and Hofstra's AD has been very public on record in the past about wanting in there too.
Either way, here's a very possible image of the college basketball landscape in 2-3 years:
-The Big 6 typical conferences
-An A-10 megaconference and CUSA/MWC megaconference
-The MVC and WCC
-About 20 small-major conferences. With the WAC imploded and the CAA dissolving as described above....Horizon without Butler....does the MAC, Sun Belt, and revised WAC leap up here? Quite possibly actually, but too early to say.
If we stay in BracketBusters, we associate with all the conferences below us and none above us. Bad news. Basketball could soon be the case of the haves and have nots, and we need to associate with the haves.
