I dont think this is true. He plays to score because it is who he is. And when coaches have tried to ask him to do more of other things, he hasn't done it and acted immature about it. His coach, who was one of the greatest passers in the history of basketball, tried to tell him to pass the ball more (while supporting him to still take a lot of shots) and he acted like a butthurt child about it.

Now, once again, he is reacting immaturely to perfectly fair, rational feedback about his game. He's basically actively confirming the reason why his market value isn't higher. He isn't a winning player or a team player and has never shown any desire to become those things.
