Seeing it in person at near court level was impressive. The other team would drive in and throw it up. Atiki would elevate making it very difficult to shoot over the top of him in help side plays. It is pretty impressive to watch a player elevate nearly to the top of the backboard to defend a shot. That has got to be intimidating for teams taking it to the rim.
Noticed the same thing on rebounds. He would jump the same time as other players and he would just keep flying upwards. Watching it in person at best court level was very impressive to see. If he can continue to develop better hands, footwork, not foul, he could really be a force.
