Heard of Kenny George before?
That guy is 7,7" (barefoot and 7,9" w/ shoes), 360 lbs, and his wingspan is an unbelievable 8,5"!!! That guy is almost unreal! He can basically stand flatfooted and dunk!
But how in the world can he let somebody 6,9" dunk on him? If you watch closely his hands are clearly above the rim while he's still standing on the floor!
