“The Photograph” star Lil Rel Howery, who grew up on the West Side, fell down trying to grab a ball early in the game. Chance the Rapper managed to dribble down the court and out of bounds without any assistance in the second quarter, and he put up an air ball in the fourth quarter. Former Chicago Public Schools CEO and former U.S. Secretary of Education Arne Duncan — a late addition to the roster — scored a few times between bouts of confusion, or perhaps exhaustion.
