Damn, that looks CGI. If ya want to check out Carter's dunking contest, here it is. The first one is my favorite, then finish off the contest with a cheap dunk...

Rajon Rondo, small guard of the Celtics stuffs it against the Pistons few months ago. I saw the game on TV but forgot about the dunk. I call this guy 'bouncing baby' because he would get back up and at 'em everytime he crashes hard to the floor
