Mountain West Conference The Mountain West Conference (MW) is one of the collegiate athletic conferences affiliated with the National Collegiate Athletic Association (NCAA) Division I Football Bowl Subdivision (FBS) (formerly I-A). The MW officially began operations in July 1999. Geographically, the MW covers a broad expanse of the Western United States, with member schools located in California, Colorado, Hawaii, Idaho, Nevada, New Mexico, Utah, and Wyoming. Craig Thompson has served as Commissioner of the MW since its founding in 1999.
Southern Athletic Conference of Indiana The Southern Athletic Conference is an IHSAA-sanctioned athletic located within Clark Harrison and Jackson Counties in South Central Indiana. The conference began in 1974 as a four school conference, and grew to eight members within five years as other local conferences disbanded. The conference has lost two schools in the years since, both left for the Mid-Southern Conference. The Southern also had schools that had dual membership in other conferences at the same time, though by 1986, all of these schools entered full membership with a sole conference.
