Celtics - receives Simons and two 2nd-round picks which was the original package
Kings - rumored to be interested, receives Jrue Holiday (who gets sent back to California) along with Kris Murray to be reunited with twin brother Keegan Murray and possibly reignite both careers.
Lakers - receive DeMar DeRozan as an occasional go-to scorer so both Bron or Luka can rest. I admit this isn't the perfect fit but they've got to get scoring from somewhere else. You might even question why not just trade for Jrue himself? They also grab Robert Williams III as a Luka lob-threat.
Blazers - receive Dalton Knecht, a shooter & Devin Carter, a defense-first guard. Both young, fits timeline and needs of the Blazers better. All the other expiring contracts along with them are for salary purposes and can be swapped with whoever.
