Okay, so this isn't exactly high school related, but I had to put this up.
Not sure if you've heard of Kenny George or not. He plays basketball at UNC Asheville and stands 7-foot-7 and weighs 370 pounds.
The guy makes Jaan Montgomery look like a smurf. And he can dunk the basketball standing up.
This video does a nice job of telling his story. Man, imagine trying to guard this dude on the court? No thanks.
