Mableton’s Collin Sexton put the SEC on alert during the McDonald’s All-American week in Chicago.

The Pebblebrook senior, an Alabama Crimson tide commit, won the event's slam dunk contest and threw up an incredible over the back alley-oop to give the East a lead at the half of Wednesday night's game.

The pass impressed NBA star Dwyane Wade, who was watching from the sidelines. (Watch the video)

Despite Sexton’s razzle-dazzle, the West team took the victory, 109-107. He had 8 points, 7 assists and 1 rebound in 23 minutes played.
