Kings are currently 15-20 and 7 games back from the 8th seed in the west with OKC likely to push for that spot as the season goes on. A sensible move would be to hold pat and not risk any future assets to win more games this season.
So fare this season sensibility has not been in style in Sacramento. So with that in mind here is my trade idea
Cs get D Williams, Stauskas, 2018 Loto protected 1st
Kings get Green, Wright and wash 2015 2nd
This would actually be two separate trades. Wright for future 1st (using their TPE) then Green + 2nd for Williams and Stauskas
Why it works
Celtics, showed interested in Stauskas during the draft process. He hasn't done much as a rookie but is a young skilled guy who was the 8th pick. He has a nice complementary skill set and could work nicely down the road with Smart. Williams is an expiring deal who may find a 4th big role if bass is moved.
Kings, its a crazy move to try to make the playoffs. Wright should compliment Cousins and Thompson well and could either start at the 4 or come off the bench and back up 4 and 5. Green is a less perfect fit but could be a stud as a high usage 6th man. Could also see them finishing games with Green and Gay at Forwards creating great spacing.
