2009 McDonalds All American slam dunk contest highlights, Video. These highschoolers are laying down dunks that would get some 8′s and 10′s @ the NBA All Star Weekend. The first shot, by Peyton Silva who is committed to Louisville, goes off the shot clock. The second dunk, by Mason Plumlee who is committed to Duke, is redunkulous. The 3rd, by Avery Bradley who is committed to Texas, is Isiah Rider incarnate.
