You could keep all the teams together in their last NBA incarnation and fill out rosters with whoever the existing players on the teams were willing to add. I'm sure that without the formal apparatus of the NBA, they'd earn a lot less money -- the installed base of arenas and basketball-promoting resources has formidable value. But I'm guessing they could make enough money playing in smaller arenas to be worth their while. And I imagine that before long, the new NBA union-cooperative teams would attract more allegiance than the empty brand names they replaced. The guys who can do the insane athletic feats have the real value.
