You forgot Grinnell College, former member of the MVC

Well if it weren't for ESPN and their cronies Pitt and Syracuse we'd all still be in the real Big East.

Other than the WAC, the western conferences seem to be more stable - probably due to lack of options - and the changes have mostly been among themselves, with several hopping conferences multiple times

Those you listed were just affiliates, not full conference members.

The A10 has lost 10 full time members and gain 14, almost the whole conference!
UMass and private George Washington are the continues members and Duquesne left and came back.

GONE
Butler
Charlotte
Duquesne

Correct. And I realize the OP said "where the school plays basketball." Just adding some additional information (in part because you wouldn't necessarily have expected those schools to have been in the BW at all).

Don't forget the Big East (1979-2013)/AAC -- 34 BB schools total so far.

Big East (1979-2013)/AAC
ACC: Boston College, Louisville, Miami-FL, Notre Dame, Pittsburgh, Syracuse, Virginia Tech
Big 12: Central Florida, Cincinnati, Houston, West Virginia
Big East (2013-): Connecticut, DePaul, Georgetown, Marquette, Providence, Seton Hall, St. John's, Villanova
Big Ten: Rutgers
Current Members: Charlotte, East Carolina, FAU, Memphis, North Texas, Rice, SMU, South Florida, Temple, Tulane, UAB, UTSA, Wichita State

Not sure if Wichita State counts as a G5 school, but it's in a G5 conference.

Good point. They slipped past my radar.
