I would draft Bender or Chriss ahead of Murray at the 3, because they are close in ranking and the Celtics are weak up front.
The trade I would like to see: Celtics give the #3 and #16( or maybe #23) to Wolves for the #5 and Dieng.
Wolves would pick Bender or Chriss at 3, Suns Chriss or Bender at 4. Celtics get Murray at #5. They get their shooter at 5 plus a center, Dieng. Wolves get the 4 they want. I doubt somebody like Dieng will be available at #16 or #23.
Wolves are looking for a real 4 to go alongside Townes. Dieng is more a 5.
