Looks like my being away from here for a while means I missed out on this one.
The back-to-backs are supposed to occur only for road pairings of less than (IIRC) 400 miles. I think that's supposed to encourage BUS travel for the short trips, though I could be wrong. Of course, one night's lodging is saved, theoretically. Loss of revenue... perhaps that would be hard to prove. Eh...
I think we all know that BSC wants schools with football. That's probably more important at this level than it is upstairs, simply because, for most FCS schools, football is equal parts blessing and curse. Obviously, Montana in this conference throws that theory off a bit.
Seattle WANTED to go to the WCC. They used to be a member. Gonzaga does not want them, therefore it didn't happen. Gonzaga LOVES having a relatively easy 8-team conference; it guarantees a successful conference schedule and maximizes the number of big payout games they can schedule. Gonzaga is Montana with tons more daring, so to speak. As such, don't expect Seattle OR Pacific (or, as many people in the Rockies and the Sun Belt Conference are begging, U Denver) to join the WCC anytime soon.
Could the Big Sky add Seattle and be successful? I think so. Does Seattle want it? Eh...
