Just think, if they strike out on Durant/Horford/Howard etc and lose Turner because someone overpays him (now looking likely) the Celtics are a WORSE team in 16-17. Spin that one to your fan base Wyc....
We would probably be able to sign somebody to replace Turner (like Dudley), but that player would have to be productive in limited minutes - we have Jaylen and Rozier to start developing. Smart would likely take Turner's role, but his minutes will probably remain the same.
The front court shouldn't change too much - we can keep Amir and JJ if all else fails. We would need to replace Sully, which is no small loss, but hopefully Mickey is ready to step up with some extra minutes. We should at lest sign somebody close to Sully's caliber for a huge one year contract.
