Misconception: Kanter is selfish.
This is speculation on my part, but to me, he seems to be immature, self-conscious, & lacking confidence/self-esteem, which has caused him to handle himself on & off the court in a manner that has made him appear selfish. I don't think his refusal to ever pass out of a double team was due to him wanting to get his own numbers, so much as it was due to his desire to help the team win (which it didn't) in the only way he knew how (by scoring), & his extreme desire for the approval of his teammates & coaches. Due to his immaturities, he was (& still is) unable to view the perspective of the situation from that of the team's, than that of his own.
