Boise State "dude" you mean? The WAC already imploded when Boise State left haha. Really, these new defects are a bigger threat to The Big South, The Big West, The Big Sky, and possibly The Sun Belt, if you ask me. The WAC will just go add from the current wish list of North Texas, Montana, Montana State, Portland State, Sac State, Cal Poly, CS Bakersfield, Lamar, Sam Houston State, etc.. If the Montana schools (a package deal) join, and Portland St, Sac St, and Cal Poly, for example, the conference will be fine in basketball, and just hanging on in football. That is, if The Sun Belt can't convince teams to join, which I see happening. La Tech is probably going to be the last team to join C*USA, maybe North Texas. If the WAC implodes (I really hope it doesn't), BSU basketball, and all the non-football sports, will probably join The Big West, C*USA, or maybe even The Missouri Valley. The school is already building good relations with Big East schools, with home-and-home series being rumored for next year (in basketball), v UConn and Memphis. This according to Memphis' AD, I believe. Maybe The Big East would be a (ridiculous) last resort. Maybe the MW will come to their senses and realize BSU is a good addition in bball. That program has a lot of potential.
One thing is for sure, there's going to be a free-for-all in the expansion race, amongst mid-majors. All because of the recent development of USU, SJ St (who cares), and likely La Tech, leaving. Not to mention, other forthcoming moves back East.
