This is just total spitballing here, as I think we're totally screwed, but hear me out anyways:
If they don't come up with the money, whose fault is that? At this point, the NBA has gone above and beyond to help Sacramento, even going so far as to having the committee recommend to keep the team there. If they don't put the money together, though, what's to stop the BoG from reversing course? At that point, the NBA has made it abundantly clear that they have done absolutely everything they can, and all of the blame would fall on the Sac investment group. The NBA hasn't officially denied anything yet. Let's just wait and see if that money goes through, keeping in mind, that no matter what, this bid and that arena plan are not feasible in Mad Max, California.
