SLU is an private, urban university which makes it a much better fit with the A-10. Also, the MVC has no schools with any kind of national reputation athletically or academically. Every kid has at lesast heard of Temple, Xavier, and UMASS (thanks to Calipari). Who outside of the midwest has ever heard of any of the MVC schools?
And as has been mentioned on this board several times, assuming our presence in the A-10 or MVC will help our recruiting in the areas these conferences are located, would you rather attract plyers from Omaha and Des Moines or Philadelphia, etc?
