My outlandish Giannis trade idea doesn't quite work, but would start with something like this:
BOS:
Sabonis, Portis
MIL:
Brown, Murray
SAC:
Giannis, and a first from MIL
MIL makes out getting Brown and Murray. BOS trades a star wing for a star big and a solid big. SAC could compete right away with Giannis + Lavine + DeRozan, plus gets a pick to bolster their future. I know this doesn't quite work. SAC probably does not do it, but food for thought.
