Why would Lakers do this?

The Lakers get a perfect big man fit for Luka, who can protect the rim, roll an is giving vertical spacing. Ayton is just not good enough to be a starting center on a team trying to be a contender. The only really big asset they give up is their 2031 Pick. But in 2031 Luka is most likely still a laker so this pick wont be lottery.

New starting 5: Luka | Reaves | LeBron | Hachimura | Okongwu

New bench lineup: Smart | Knecht | SF and PF Svi/LaRavia/Niang/Vanderbuilt | Ayton

---------------------------------------------------------------------------------------------------- Why would Hawks do this?

The Hawks get a Allstar - level player in their roster, finally making them a contender in the East. Giving up Okongwu + good role players is hard, but making that final step will be worth it.

New starting 5: Trea | Risacher | Johnson | Lauri | Pingis

New Bench Lineup: Krejčí | Daniels | Thiero | Newell/Love | Hayes

Why would Jazz do this?

Jazz get 1. Pick and a high upside swap for Lauri which is good for tanking. Also they get back many good role players you can trade for Picks or young upside talents in the future.

New Starting 5: George | Walker | Bailey | Filipowski| Kessler

New Bench Lineup: PG and SG: Collier/Vincent/Clayton Jr./ Kennard |Sensabaugh | Hendricks | Nurkic
