6. Josh Smith
Watching Smith over the past few seasons, he doesn’t seem to have quite the same lift that he did back in the day. But even if he did lose a little bounce, that only means he’s hitting his elbow on the rim instead of his shoulder. The best lefty dunker in the game, Smith’s signature dunk is rivaled only by LeBron’s in it’s unblockability. For someone so big and long, Smith is a phenomenally quick jumper, finishing last year with 98 dunks, many of them on tip-ins.
