Why Bucks do this: Seems like something Giannis would call for, with brook lopez being an UFA, the contract gets smaller on resigning, so less of an issue.
Why Celtics do this: Get a younger player and salary relief, and a pick which can be maybe valuable? Just in time for tatum to come back, they semi-tank for the one year, after trading KP in another trade.
Why Detroit do this: More draft capital for taking pat's bad contract, and they get a much needed backup sg to cover for ivey until he's back. Also improves the 3pt shooting of the team arnd cade.
