Lakers - Get Kai, a dramatic boost to offense. Also, Poeltl is a sneaky win, because he can be a defensive anchor at center, which lets AD and LeBron both be roving/switching defenders, dramatically improving the defense ... and the reason AD wants to play with a true center.

Nets - This is about Ben Simmons. He gets to be a point guard on offense with two more quality shooters, and he can still be a roving/switching 'big' on defense (with Claxton providing the defensive anchor at center). Also, the team gets an $11mil trade exception and an extra first to get a good trade.

Spurs - they swallow the Westbrook contract, let him join another team, and they get two picks out of it.
