kadour ziani is a FREAK…watching one of his dunk remixes is definitely worthwhile. I have to believe that he can get close to 50" off the ground with a running start. Look at the dunk in the video posted above where he throws himself an alley-oop and dunks it with two hands (in black and white). He can also wedge a ball between the rim and the backboard and kick it out with a normal running jump (no backflip involved).
