Two days ago I read some Phoenix fans calling him "a locker room cancer".
I read that too. I think it had to do with him complaining about not getting a shot to start.
He also said he didn't trust the suns management. or something along those lines.
In addition when he came in during games, to lead the 2nd unit, he took away pg duties from Dragic.
It was a mess in phoenix.
Nobody knows the whole story relating to the firing of his agent but I think the Agent he fired gave him assurance that he will start or have a good chance to start in Phoenix. But the Suns were mainly concerned in the offseason to try to keep Bledsoe and Dragic together. So maybe he felt misled that the only reason the Suns wanted him was to come off the bench/insurance purposes.
Maybe if he knew the suns mindset from the beginning he would of signed with another team , even if it meant for lesser money. Maybe he would of even signed with the Celts.
