Boston Celtics coach Joe Mazzulla looks on during the first half of a game earlier this season at TD Garden.

Inside the Boston Celtics’ locker room after their win over the Nets on Wednesday, Joe Mazzulla sent his players off with some parting words before they headed out for the All-Star break, and then asked the room if they had anything to add.

Jayson Tatum, from his corner stall, then stood up and approached Mazzulla with the game ball.
