I’d get absolutely clowned on if I posted this on r/NBA, but the Mavs best move might be to consolidate their 3 end of rotation guys (THJ, Green, Kleber) into a single dominant scorer who also happens to be a distressed asset… Zach Lavine.
Having a $43mil salary as your 6th man would be unorthodox, but that backcourt would be near unstoppable. Three guard lineups would also be a sight to see when the situation called for it.
You’d have to convince Derrick Jones Jr to take $5.1mil on a 1+1 contract though, which would be easier said that done.
Aside from that, the Mavs only realistic options right now are Jerami Grant… Malcolm Brogdon… Corey Kispert… MAYBE Bobby Portis. Potentially Jonathan Isaac or Naz Reid as Kleber upgrades if the stars align. All are flawed, and I’m not sure any of them push the Mavs into titles contention against the Celtics. We’ll see what the Knicks, 76ers, and Thunder do too because they all have war chests I expect them to open.
They don’t have many avenues to upgrade this offseason, so other than a Hardaway salary dump to free up money for DJJ, I expect them to run it back.
