I think Wichita State just wants someone near them. If Missouri State boogies for FBS, the Shockers become a noticeable geographic outlier.
Unfortunately, there isn't any other school from Kansas in the FCS or NFS (non-football subdivision) levels. The only ones are FBS level status (Kansas and Kansas State). Wichita State should also upgrade into FBS someday, if the Shockers plan to re-instate football after dropping it since the MVC quit sponsoring that sport.
At this point, ANY western program would help them just a bit...be it the unlikely, like Saint Louis and Denver, or the potentially unwanted, like Oral Roberts, WIU, or the Dakota State schools...
...still better than UMKC.
How about schools like Nebraska-Omaha? In case the MVC wouldn't re-instate football by absorbing the MVFC and UNO's plan to revive its football program, it'll be fit for the MVFC while competing its other non-football sports as an all-sports full member within the MVC. Might also help "representing-replacing" what's left in Creighton.
