Remaining WCC teams : St. Mary's, USF, Santa Clara, Pepperdine, San Diego, LMU, Portland and Pacific.
Big West Teams: Irvine, San Diego, Davis, Long Beach, Riverside, Northridge, UCSB, Bakersfield, Cal Poly and Bakersfield.
WAC: Tarlton, UT Arlington, Seattle, Utah Valley, SF Auston, A. Christian, Utah Tech, Southern Utah and Rio Grande.
Take the best two of these considering facilities, history, current quality and market. That gives each team 20 conference games leaving loads of room for a quality OOC. Travel costs would be minimal.
My two would be St. Mary's and USF.
