This list is far from a slam dunk
Notable omissions: Darryl Dawkins, Shawn Kemp (aka The Reign Man), Tom Chambers and Kevin Johnson, who threw down a particularly nasty one over one of my childhood heroes, Hakeem Olajuwon.
Also, though few people can remember what the NBA was like back in the early '90s, another name I'd like to add is Robert Horry. Back in his more youthful days with the Houston Rockets, "Big Shot Rob" had plenty of hops and wasn't shy about cramming it on folks.
Oh well. Feel free to offer your own suggestions.
