We continue Jack History Month today with a quick fact that you might not have known about the Pittsburgh legend. In High School the Jacka won a dunk contest. I know it sounds crazy. We remember the Jack as big guy, who couldn’t have been too athletic. It turns out despite his size many of his close friends knew him to be fairly athletic. Of course in high school he was much smaller than he was at the height of his rap career. Check out the Jack Fact which comes courtesy of his close friend Montana.
