Chris Boucher's gesture, breaking an unspoken rule, after hitting a 3-pointer at the buzzer, left Westbrook and Joe Mazzulla displeased.

Celtics star Jaylen Brown rested against the Kings on Friday night, and Joe Mazzulla said that benefitted the All-Star in multiple ways.

On July 2nd of last year, Boston Celtics guard Derrick White was celebrating his birthday with a relaxing round of golf. Then Celtics head coach Joe Mazzulla called him, but not just to wish him a happy birthday.

The Boston Celtics never seem to take a night off. They play hard on both ends of the floor every game, giving max effort for a full 48 minutes. It’s a big reason why they’ve managed to stay so successful this year without Jayson Tatum.

Mazzulla was not the only Celtic supporting the Patriots at TD Garden Monday night as team owner Bill Chisholm sported a ‘I love Drake Maye’ shirt courtside. Patriots owner Robert Kraft was also in attendance for Monday’s game and got a loud ovation from the Garden crowd when shown on a jumbotron during a timeout.

Jeo Mazzulla had a heated moment with the referee for a disputed call during the Celtics vs. Hawks recent game.
