Realistically, it is difficult to see the "C-USA 4" being the basis for a formation of any conference, unless of course an existing conference were raided of 6 members and the new conference would be able to obtain an automatic NCAA bid without a five-year waiting period. Other than the Horizon League, any prospective conference to be raided (e.g. A-10, CAA, MVC, Sun Belt) features a combination of football and non-football playing members, and this could further complicate the situation....
Schools not currently offering scholarship football:
A-10: Dayton, Duquesne, Fordham, George Washington, LaSalle, Saint Bonaventure, Saint Joseph's, Xavier
CAA: Drexel, George Mason, UNC-Wilmington, Old Dominion, Virginia Commonwealth
MVC/Gateway: Bradley, Creighton, Drake, Evansville, Wichita State
Sun Belt: Arkansas-Little Rock, Denver, New Orleans, South Alabama
No offense to the Marquette faithful for the performance of this past year, but I am not sure that a conference built around the C-USA 4 could guarantee itself that an at-large NCAA bid would be available every year during the five-year waiting period. The only conferences that could feasibly be raided of a 6-team contingent (that did not offer scholarship football) are the A-10 and the Horizon League. I don't see A-10 programs like George Washington and Saint Joseph's sacrificing what they have now for a conference with a "midwestern" orientation. The quality of play in the Horizon League notwithstanding, 3 of its 9 members are in existing C-USA 4 markets (e.g. Illinois-Chicago, Loyola, Wisconsin-Milwaukee). 6 members could be stripped from the Horizon League without creating a direct market overlap (Butler, Cleveland State, Detroit, Wisconsin-Green Bay, Wright State, Youngstown State), but Youngstown State plays scholarship football, and the exclusion of the 3 programs would negate some relatively quality basketball programs (UIC, UWM).
Is the "C-USA 4 Pact" merely rhetorical bluster emanating from Charlotte and possibly Saint Louis? Would a proposed "all-Catholic conference" feature a lone, public (and Southern) school? It just doesn't appear to be adding up...Charlotte is too geographically isolated from the other three to make me think such an agreement actually exists.
