Mazzulla was officially named the organization’s 19th head coach last February after Boston removed the interim tag from his title.

Mazzulla took some heat in his first season as head coach for his management of games, but the Celtics have looked like the best team during the 2023-2024 NBA season.

"I don’t know about the minutiae of managing games, I just know that they have played very good basketball this year," Miami head coach Erik Spoelstra said on Sunday of Mazzulla and the Celtics. "They’ve been the most consistent team all year long. They present some challenges for sure offensively. They can spread you out. They attack."

"And then defensively, I think they’re just very underrated. I don't think enough people talk about how stable and good their defense has been this season."

Boston has won the first two of their three games against Miami this season.
