I agree with Rondofan. Starters should be Kanter, Hayward, Tatum, Brown and Walker. This is a pretty small lineup, especially at PF. They will have to play great team defense. Rotational contributors will be Smart, G. Wil. , Theis and Edwards. I see Wannamaker, Poirier, Semi, Langford and R. Wil. as essentially non factors, but hope I'm wrong about Semi and R.Wil. Yabu will be traded. The Celtics will need to acquire an upgrade at center ... a rim protecting big, who can rebound, if they want to be a legit contender.
