A kid from my high school, started 4 years at Iowa at CB and was all-big ten.. Jovon Johnson. I came to the school the year after he graduated and it was pretty well known he'd be in the NBA if he wasn't a manlet.
He was no more than 5'6 max and I use to watch him come back to my high school in amazement with some of the dunks he did. I am sure this guy is probably better, but it just shows you how great of an athlete some people can be regardless of height.
If he was white, he would barely touch net on good days.
