Melo is undeniably a great talent, who can score a myriad of points when given the ball. The only thought I have is he doesn't score more often than not. Even more, he's a putrid defender. He is by no means a team player, and I don't think his attitude or presence are in any way necessary for the success of the Knicks.
I'm not saying trade him, because that's a very knee-jerk decision to a losing streak. What I am saying is that Melo is no LeBron, or DWade. I categorize him as a much better version of Monta Ellis in the sense that he needs the ball to score and make an impact. He's not a plus defender, not a plus passer, not a plus rebounder. And when things aren't going his way his first inclination is to huck up some threes or point the finger at someone else. He's not a winner.
