I don't know about the specifics, but it's undeniable there are a lot of mutually interesting options that would point to a deal with Charlotte.
Charlotte badly needs a C, defense, and veteran leadership. Has PJ Washington, Kai Jones, 13 + 15 picks
SA badly needs frontcourt athleticism, potential and depth. Has Poeltl, Josh Richardson, Toronto (20/21), Boston (23/24/25) & LA (38) picks.
I'm not suggesting to deal everything for everything, there could be multiple scenarios that would be beneficial for both without compromising too much. What I am saying is that there is too much common ground for a trade not to explore it further.
