Lakers turn D-Lo into the frontcourt help they said they want. Added Reeves just so they have another inexpensive warm body in the backcourt.
Now that BI is willing to sign a 2 year deal, he's tradable if he gets healthy before the deadline. He fits in SA as a playmaker/ initiator while Castle grows (and once CP3 leaves). SAS just gives him the money they were gonna give Barnes + Collins anyway-- classic consolidation deal for them. BI starts at the 3. Matko another back-up C.
Grizzlies upgrade Kennard into Barnes, Konchar into Green.
Pelicans turn BI into some meh picks. Konchar's contract isn't that bad, you just consider it part of the price of the picks.

SAS might be giving up too much draft capital. LAL might be giving up too little. The draft picks are always the hardest part to make work, but there's enough between these 4 teams to make something work.
