Las Vegas is still USC territory, plus UNLV will have difficulty in getting support from Stanford, Cal, and even USC academically. Like it (or aware of it) or not, USC is a school with academic chops and gets research money. Iowa State is possibly the least desired athletic program from a public university within the current BCS conferences. As a whole, only the private schools like Vandy, Duke, and Wake are at or near the same level. UNLV is actually one of the leading theatre and arts schools in the nation. Plus, the only other realistic option to have a 16th team would be UNR, and I think they would rather have the LV tv market. It's only USC territory right now because UNLV is not part of the same conference. Trust me, if UNLV joined the Pac-12, their football program would explode (in a good way). I think the Pac12/Pac16 would rather have San Diego State than UNLV.
