4.72 40-yard dash with a 4.46 shuttle and a 28 vertical at the US Army National Combine - in January (though he has a listed time of 4.62). Thats not exactly blistering speed but not glacial either, especially for his size.
Compare to someone like D'Anfernee McGriff - a 6'1" 230lb who runs a frikken 4.34
Man, after watching this 3,000 yds.+ kid's highlight video, I can't believe he's a 3-star. He's got great lateral moves and seems to take it to the house every time he touches the ball.
