Hawks: they move on from two starters who don't seem to be a part of their long term plans for the hottest 3 and d wing on the market right now. Plus they add bench depth with 3 rotational players and only give up one protected first.
Raptors: they get a rim protecting big and balance the roster to compete in the future, while also adding two firsts to add assets for punting on this year. They could look to trade Fred or Trent to get even more assets if they want
Rockets: they buy low on a talented young player on a high contract, and clear some of the log jam by trading off two veterans who don't fit the timeline. Rockets buy out Holiday, he could even return to the hawks to finish the year. The fit is a little interesting with jabari but if you run alot of the offense through sengun it could work.
