Dallas get a great wing defender with a good handle for a big man and good scoring with lots of potential. And some salary filler.
Warriors get two good young players who can play rotation minutes and 3 1sts for kuminga. And get off looney who's done.
Okc get the defensive big man they need with rebounding rim protection and great lob catching and lots of potential to grow and a young big athletic first rounder to develop alongside their young players. And a second maybe make it 2 seconds if needs be.
I think this could get it done but it's close.
