Kenny George:

7,7" (91 inches) barefoot
360 lbs
A whooping 8,5 (101 inch) wingspan!

He's plays for the NCCA right now for the Bulldogs, and he's capable of literally dunking the ball just by standing underneath the rim, barely even having to go on his tippy toes! If you don't believe me, just watch the folllowing youtube.vid!

vs.
Sun Ming Ming
Height: 7,8-7,9" (I am not sure if this is on barefoot or in shoes)
Weight: 370lbs
Wingspan (I am not sure but it appears that the span of his arms is surprisingly slightly shorter than his height which is rather unusual).

Also, despite being possibly slighly taller than Kenny, it seems like Sun can't dunk without leaving the ground (or not as easily).

Who do you think is the better all around baller and has a better chance of being drafted for the big league?
