The crazy thing about that dunk where he alley ooped it to himself from behind the backboard was that if he had jumped any higher, his shoulder would have hit the backboard itself. So in effect, he could not have possible jumped any higher. That means that only players with arms as long as his will ever be able to duplicate that dunk. Also, his head was actually behind the backboard. The 2nd dunk was pretty spectacular too. It was really fun to see a player pull off such amazing stuff without all the failed attempts.
