Lakers get all the guys they want (Derozan, Russ and Buddy) and then bring in a center that will be a better fit than Drummond.

Wizards get some young guards for Russ

Spurs agree to send Derozan to LA and acquire some players and picks. They get Kuzma (who they want) and sign and trade Dennis.

Kings also get some players and some picks (get out of a long term Buddy Contract and take on some expiring deals and less expensive deals to create cap flexibility in the near future).
