I agree with placing him 12-15. I'd probably have him closer to 15. I think Duncan and LeBron are both comfortably ahead and I would at least consider taking a prime D-Wade over a prime Kobe (Kobe is obviously ahead of D-Wade in the pecking order because of his durability).
Gonna have to disagree with
@Deepster 's assertion, though, that he wasn't must-see TV at his peak. He was certainly emblematic of an era of basketball that I'm not terribly disappointed that the NBA has moved beyond, but I've seen him convert opposing fans to mesmerized spectators like no other player in the history of the game besides maybe Jordan. He inspired awe and fear (to some extent, in Lakers fans, too) for the reason that there was no shot he wouldn't take and no shot he couldn't hit. I was never his biggest fan, but he'll deservedly be remembered as one of the great athletes and entertainers of our time.
