Seattle and Utah Valley are on the short list for the WAC. Right now there seems to be more buzz about Seattle, but geographical pairings and the addition of football members (i.e. Lamar, Portland State, etc.) may dictate who gets in the WAC, even if it is only a matter of timing. I have a feeling both will get in once a ninth football member is lined up, as 9/12 just works too well for scheduling:
WAC West - Seattle, Idaho, San Jose State, Utah State, Utah Valley, Denver/Football #9
WAC East - New Mexico State, Lamar, UTSA, Texas State, Louisiana Tech, Denver/Football #9
Houston Baptist and UTPA (and even the Sun Belt's UALR and the Summit's Oral Roberts) would be better off in the Southland once the Southland realizes FCS football enables the WAC and Sun Belt to keep restocking through them. If the Southland loses Lamar, they ought to bring in HBU, UTPA, and UALR. If any of those three start FCS football, it keeps Southland Football alive longer. If not, they'll be the stable ones once the WAC and Sun Belt come a-knockin' down the road. Ideally, the Southland adds UALR, UTPA, and HBU once Lamar departs to get back to 12 schools (7 for football-FCS requires only 6 schools).
Southland West - UT-Arlington, Sam Houston State, Stephen F. Austin State, TAMU-Corpus Christi, UTPA, Houston Baptist
Southland East - Nicholls State, Northwestern State, Southeastern Louisiana, McNeese State, UALR, Central Arkansas
That leaves us with Chicago State and NJIT. Chicago State should try to join the OVC, which would give the conference a presence (albeit minimal one) in the nation's third largest market to go with a presence in Nashville (should Tennessee State stay) and suburban St. Louis (SIU-Edwardsville). CSU's shot at the OVC will ultimately hinge on the fates of Tennessee State, Jacksonville State, North Alabama, and possibly even Northern Kentucky.
NJIT needs to become the tenth member of America East.
That only leaves Longwood and Bakersfield State as a true independents.
