Bringing another guy in the "buy ouT" will make Celtics very very strong.
Ainge knows what he is doing. Ainge has to balance his role being a GM, has a responsibility to the make the team competitive and to profit. He thinks Celtics has no future retaining Perk, Nate, Haragondy, Daniels & Semih. He re-arranged the living room by bringing new furnitures for next year... yet capable of bringing the 18th banner too.
I also thinks, they are milking Shaq & JON's injuries preparation for the last run.
The buy out will be another surprised for us...sort of advance Christmas gifts.
