I know that's the policy or focus of the presidents. I don't see why fans should care about that.
2,000 Boise State fans traveling to a game in Fort Collins is more fans than usually will travel from Denver for a game in Fort Collins.
Maybe 2,000 is decent by MWC standards, but not ready to step up to P5 standards. Especially if you're trying to make the argument that Boise's small market size is irrelevant because they have a national fanbase.
IMO, Boise is popular because they're the little school that could. Move them up to P5 and after a while that dissipates. After that they're Wazzu with a smaller alumni base.
