Guys, I've also heard the rumor about Portland State trying to go WAC, but it is NOT happening. Period.
First off, what's in it for the WAC to take a program that isn't even successful in the biggest $$$ making sport (football)? Portland State doesn't even have a stadium anymore now that PGE Park is being converted to an MLS stadium--- but even when they had a place next to campus, they were drawing 5,000. They'd need to go 5x above that to even be considered as viable in FBS.
Second, and perhaps more important, is that the $$$ required to build programs goes up exponentially in the WAC. They don't have enough to barely support their FCS program, so they sure aren't going to be jumping off a cliff to go up 5x and deal with the Title IX fallout.
I don't know this, but I'll bet the same is true for Sac State. At least it would appear that way from the outside.
