I would do this trade
http://www.espn.com/nba/tradeMachine?tradeId=y6cy84t8To Kings: Smart, Theis, Nesmith, Waters, a protected 1st and 2nd
To Celtics: Barnes, Whiteside and 2 fillers
Barnes is a player Danny has had an eye on since HS. He has won a ring, plays good versatile D, good clean 3 point shot, doesn't need to launch shots, plays within himself. Probably the best complimentary piece you could find for Tatum/Brown/Walker championship pursuit
He is also signed up for the next 3 years.
New lineup
TT
Tatum
Barnes
Brown
Walker
Timelord/Whiteside
Gwilliams/Semi
Langford
Teague
Pritchard
With the luxury of having one of the starters on the court at all times
