Check out the runner up of the Washington D.C. Sprite Slam Dunk Showdown, 6'3" Roscoe Johnson. Roscoe easily has one of the HIGHEST verticals we have ever seen, if not the highest. Check out some of the ridiculous dunks that he put down this past weekend including an insane 360, off the toss windmill where he split his head open after hitting it against the rim, an elbow windmill and many more!
