I've been a Green apologist since he came here, but if his attitude didn't change this season, it never will.
He had the heart and soul of the franchise leave. He had Rondo injured most of the season. This was his chance to show everyone (and himself) he can be "the man." We weren't even expecting him to take us to the playoffs. Just lead the team. He couldn't be consistent, often barely showing up (I know this all too well as I made the mistake of drafting him in my fantasy league).
He doesn't have the makeup to be a star. As talented as he may be, he will always be a role player.
I don't care if he stays or he goes. Nice kid. Good talent. Just doesn't have the mentality to be a stud.
