Ben Simmons, who played one season at Louisiana State before being selected first overall in the 2016 draft, had 27 points and 10 rebounds, dazzling the crowd with a handful of explosive, driving dunks, including a reverse jam along the baseline that had the 76ers cut the deficit to 108-107 with 7:26 left.
