When the Celtics handed Joe Mazzulla the head coaching job in September 2022, the decision was born of crisis, not conviction. Ime Udoka's suspension left Boston scrambling, and Mazzulla — then 34, with zero NBA head coaching experience — was the internal option that required no search committee. Now, four seasons later, he has joined Red Auerbach, Bill Fitch, and Doc Rivers as the only Boston coaches to win the NBA's top coaching honor.
The award validates what the Celtics' front office has quietly believed since Mazzulla's first full season: that his unorthodox methods — the relentless three-point volume, the positionless lineups, the almost pathological calm under pressure — were features, not bugs.
The case for Mazzulla
Boston's regular season was dominant by any measure. The Celtics posted the league's best record for the second consecutive year, maintained elite offensive and defensive ratings, and did so while managing minutes for their core players ahead of the postseason. Mazzulla's rotations drew criticism at times — his willingness to play Kristaps Porzingis extended minutes worried medical staffers — but the results were undeniable.
More impressive was how Mazzulla adapted. After last year's championship run relied heavily on isolation scoring, this season's Celtics moved the ball more efficiently, ranking first in assist rate. The evolution suggested a coach still learning, still tinkering, rather than one coasting on a proven formula.
The skeptics' view
Mazzulla's critics have never fully disappeared. They point to Boston's talent advantage — Jayson Tatum and Jaylen Brown would make most coaches look competent — and argue that the Coach of the Year award historically rewards team success over individual coaching brilliance. There's some merit to this: coaches of championship-caliber rosters rarely lose these votes.
But the counterargument is equally strong. Mazzulla inherited a team that had just lost the Finals and was reeling from a scandal. He stabilized the culture, implemented his system without alienating veterans, and delivered a title in his second season. The award recognizes a body of work, not a single tactical innovation.
Our take
Mazzulla's Coach of the Year award is deserved, even if it arrives with the usual caveats about roster quality. What separates him from other coaches blessed with talent is his willingness to be genuinely weird — to challenge conventional wisdom about shot selection, rest, and in-game adjustments. At 36, he has already won a championship and now a Coach of the Year trophy. The question is no longer whether Mazzulla belongs among the league's elite coaches. It's whether he can sustain this level while the rest of the league catches up to his methods.
