Marcus Smart/Avery Bradley/Jae Crowder/Jaylen Brown/Al Horford
Defense! Dee-fense! This lineup’s primary strength is defense, with all five of these guys able to guard multiple positions, and some—like Marcus Smart—able to defend all five positions. This lineup has the Celtics’ three most well-rounded players in Bradley, Crowder and Horford, so it shouldn’t sacrifice offense for defense. It also has Brown, the Celtics’ highest draft pick in two decades and a player fans can’t wait to see in action.
