Well, maybe some players would say no, but that wouldn't be anyone, that we would actually want to play for the Celtics.
First of all, I don't believe anyone should choose their team based on one player's reputation. If the Celtics was interested in my talents, I would be very flattered. If I was hesitant because of KG. I would talk to someone who had actually played with KG, before I made any judgement.
Some players genuinely don't like KG (probably because he got under their skin), and some of them would say no because of that. But that would not be based on reputation.
