Every year in training camp he talks about how he needs to get better on defense to improve his game, and that's not some coached answer. It's true he's not the sharpest penis in the vagina, but he's cognizant enough to know that defense is half the game and he doesn't play any. And yet he doesn't do anything about it. And while it's also true that he spends a lot of time in the gym honing his offensive craft, it's a form of laziness to not devote some of that time to work on his d. Even Dirk has overcome his limitations to become an adequate defender. Amare can't do anything about his lack of basketball IQ, but he does suffer from mental laziness.
Carmelo Anthony is an example to me of a guy who became a complete player because of dedication to his craft, after being a one-dimensional guy who only cared about scoring, and he's not exactly a Rhodes Scholar himself. What's Amare's excuse?
