I would really keep KOQ and CLee.
They're hard working players and the type of guys you look to add in FA anyway. To me it makes no sense to trade them this year. I would keep them around. Jennings, too.
We need SOME continuity and keep the guys who play hard and embody the type of team we want to eventually be.
We'll still lose plenty of games if we keep those guys. To me you keep:
KP (obv)
Willy
Kuz
Holiday
CLee
KOQ
Jennings
guys to play more minutes to see if they're worth keeping
Baker
Plumlee
N'Dour
I would certainly look to move DRose, if possible and Noah (though I doubt that is possible). And Melo. It'd be nice to get a pick or two for DRose and Melo
