Brooklyn probably says no, and I'm not sure if the warriors would throw that pick in.
But reason it could happen...
Raps get the GROAT and two young studs to develop.
Brooklyn gets Schroder, picks, and stays competitive allowing other young centres to get more minutes.
The warriors get a legit Centre and some veteran backups with playoff experience.
Charlotte gets a slightly younger old point guard on an expiring. I'm not sure if CP is coming back soon enough for this to happen.
