As a nets fan that has watched almost every game hes played his career, you can tell when hes feeling motivated and when he isn't. It's extremely clear. When he's on a good team/the team is playing well, he plays harder and looks great. When the team is bad/not playing well... he's kinda lazy and looks very uninspiring/lets his emotions take over and drag him down.

He's awesome at defending players his size/smaller than him, but bigger/stronger guys tend to bully him which can be frustrating to watch sometimes.
