I think the more you hear Gonzaga mentioned in these discussions, the worse it sounds for UConn. When people refuse to decouple them, it's the ultimate tip-off that they're not actually being seriously considered as a full member. Otherwise, they'd be floating at least one other non-football school to keep the numbers even.
Now, could UConn emerge as a compromise option if the football and basketball factions are split on the topic of partial membership? Perhaps. But I think that's less likely if the next two adds are Colorado and Arizona, as has been rumored. Those are two pretty pedestrian football programs, meaning the resistance to taking a flyer on UConn would likely be higher.
Best case scenario for UConn, as was mentioned earlier, would be for the Arizona/ASU thing to get politicized to the point that both become untenable (which seems plausible) and for Utah to opt to stay put (also plausible). As of now, Colorado seems to be the only school with its bags truly packed.
