I started thinking about Pacific ONLY because I thought about Hawaii. Truth to be told, I don't have to think about either.
Gonzaga only became a part of this fiendish plot because they might be the least likely among the core 8 WCC schools to lack ambition. Moreover, Seattle's involved only because I figured I need some sort of core of existing WAC schools to pull this off.
If I don't, if I could really cherry-pick in this situation...
Boise State (Taco Bell Pavilion, 12,380 seats)
Brigham Young (Marriott Center, 22,700)
Fresno State (Save Mart Center, 15,544)
Nevada (Lawlor Events Center, 11,784)
Nevada-Las Vegas (Thomas & Mack Center, 18,776)
New Mexico (The Pit, 17,126)
San Diego State (Viejas Arena, 12,414)
Seattle (Key Arena, 17,072)
Utah State (Dee Glen Smith Spectrum, 10,270)
With possible considerations to:
Hawaii (Stan Sheriff Center, 10,300)
New Mexico State (Pan American Center, 12,482)
Portland State (who would have to rent at least 10,000-seat Memorial Coliseum... it's a longshot that they could fill it)
Wyoming (Arena-Auditorium, 15,028, perhaps the most overbuilt facility in America)
Utah State seems like the cultural misfit here, but they FILL the Spectrum.
Seattle seems like the misfit amongst this establishment, but they do have a basketball history and they have a team that the WAC should look out for when they join. They've pulled off some games since restarting the program.
