Wow, this seems like hyperbole to me. I've been ecstatic with Kanter's defense. The guy moves laterally like MC Hammer, and plays pick and roll defense 100x better than Al. He gets in passing lanes, blocks about a shot and a half /game/36, and defensively rebounds everything (how many offensive rebounds did Al give up last night). The only thing that he does do is doesn't rotate perfectly every time, but he is damn good already, and he occasionally boxes out his man rather than taking the guard streaking to the basket. He'll learn on both of these when he watches tape. Watching him play defense on Bynum and Gasol was a joy, denying post position, entry passes, and generally bugging them. At 19, he is already more advanced than a lot of NBA bigs on D.
