There are bajillion threads so I will put my latest idea here.
JB To Charlotte for:
Diabate
Connaughton (salary purposes for Charlotte)
4 FRPs
While Diabate is valuable, Charlotte just traded for Naz Reid, has Kalkbrenner, and just drafted Hannes Steinbach with pick 14 on Tuesday, so Diabate should not be untouchable. JB will provide the gravity the Hornets need to get their open 3s in a way that Brandon Miller is not yet ready to do.
The Celtics, in addition to getting a solid center who is at least equal to Queta, get a bevy of picks. But they also get either a $57 million trade exception, or, even better in my mind since they are taking back only $6 million in salary, $32 million in cap space (once they have waived Banton, Shulga, and Williams). They would have a bunch of choices on how to spend it. My preference would be poaching Peyton Watson from Denver, which cannot afford to match a large offer (would not give him all $32 million tho), but getting in on Norm Powell is an option, as is offering LeBron $32 million to be a mercenary. They would also have the $9.4 million room exception to add a reserve (I would be happy to reunite with Simons at this number).
Any extra cap space they have after their signing could be used to renegotiate and extend either Pritchard or Queta, giving them an early raise now in exchange for a lower salary in the future.
Ideally this would allow the Celtics to turn Jaylen into Watson, Diabate, and many first round picks while resetting their financial situation for the long-term.
