Overview

  • The Celtics did not disclose the length or financial terms of Mazzulla’s new contract when announcing the extension on August 8, 2025.
  • In three seasons as head coach, Mazzulla has guided Boston to a 182-64 regular-season record and a 33-17 playoff mark, including the 2024 NBA title.
  • At 37 years old, he is the youngest head coach to win an NBA Finals since Bill Russell led the Celtics in 1969.
  • Boston has moved veterans Jrue Holiday and Kristaps Porzingis in offseason trades and appears unlikely to bring back Al Horford under its new salary-cap constraints.
  • Star forward Jayson Tatum remains sidelined after tearing his Achilles in the Eastern Conference semifinals and could miss most of the 2025-26 campaign.
