Could it be that Ainge is acquiring these players after they have been around the league long enough to understand the game while approaching their prime of their mid-20's while letting them move on once they get soft from getting paid like Turner, get fat from being Sully, reached their apex and have leveled out in Crowder, or chewed them up and spit them out when they had nothing more to give like Isaiah? It seems to me like Ainge isn't receiving nearly the amount of credit that he should for bringing these players to Boston at a time in their careers when they could help the Celtics......then once they could no longer help them simply led them out the door. Is that the coach or the GM's player evaluation?
For every player who had their best years in Boston for whatever the reasons listed above there are more who were who we thought they were #dennisgreen......Olynyk, Jordan Crawford, Amir, Jerebko, Zeller, Jeff Green, Rondo, Horford, Morris, Monroe, Baynes, etc etc.
