High school senior Ben Simmons is the top-ranked player in the country, and he has yet to lose a single game in high school. Simmons, from Melbourne, Australia, is committed to LSU, and recently threw down an insane self alley-oop at the City of Palms Classic (where he is the reigning MVP). The bench reaction was amazing.
Suns guard Gerald Green made a similar play against the Magic earlier this season, but he very obviously traveled. Advantage: Simmons.
