76ers waste opportunity against Celtics with miscues on the margins in Game 3

PHILADELPHIA — With each dagger 3-pointer the Boston Celtics hit, the angst in Xfinity Mobile Arena got louder.A sellout and electric crowd in Philadelphia had seen a Sixers team fight for almost 48 minutes. The echoes of the past walked through the building, only fitting in a Philly-Boston postseason rivalry. There was Allen Iverson. There was Julius Erving. Philadelphia Eagles first-round pick Makai Lemon rang the pregame Liberty Bell. Theo Ratliff walked laps around the building with his family. The ambiance and energy were incredible.Advertisement
