Joe Mazzulla has officially won the 2025-26 NBA Coach of the Year award! He secured the Red Auerbach Trophy after leading the Boston Celtics to a stellar 56-26 regular-season record and the No. 2 seed in the Eastern Conference. This victory officially cements him as the youngest recipient of the Red Auerbach Trophy in over half a century.
The narrative of Mazzulla's award-winning season is anchored by an incredible turnaround after a brutal start. Following the offseason departure of key championship veterans due to financial restraints, the Boston Celtics opened the season completely out of sync, losing 7 of their first 12 games. Mazzulla completely stabilized the locker room, leading the team to a dominant 51-19 run over the remaining 70 games.
Under his direct system, Boston finished as an analytical powerhouse, ranking 2nd in offensive rating (120.0) and 4th in defensive rating (111.7) globally. When franchise superstar Jayson Tatum went down with a torn Achilles, local and national media widely wrote the Celtics off, explicitly labeling 2025-26 as a "gap year" in their championship window.
Mazzulla completely ignored the external noise, leaning into roster depth and building a brand-new system centered around Jaylen Brown. Instead of dropping into the draft lottery, the team secured their fourth consecutive 56+ win regular season under his tenure.
Joe Mazzulla gives classic ‘Mazzul-ism’ reaction to his win
Joe Mazzulla winning the 2025-26 NBA Coach of the Year award is the ultimate manifestation of his eccentric, team-first "Mazzulla-ism" philosophy. His response to winning the league’s highest coaching honor completely bucked traditional acceptance-speech decorum. Before the trophy was even polished, Mazzulla explicitly tried to kill the media momentum surrounding his candidacy.
During a pregame press conference in late March, a reporter asked him what winning the honor would mean to him. Mazzulla responded with absolute disdain: "I don't need it. I think it's a stupid award. They shouldn't have it. It's more about the players. It's more about the work that the staff puts in. It's just that simple. I don't ever want to be asked or talk about it again. It's just that dumb."
He later told CelticsBlog that he hadn't "made one basket" or "gotten a block" all year, emphasizing that the focus should be on the players and staff. Upon officially winning the Red Auerbach Trophy, Mazzulla doubled down, releasing a statement requesting the NBA rename the award "Staff of the Year" to honor the team's behind-the-scenes staff.
On the NBA Showtime broadcast, he redirected attention to the team's support staff, including video coordinators and his assistant coaches. He expressed that he is "forever indebted" to the assistants who sacrifice time with their families. Rooted in his unique, team-focused philosophy, Mazzulla explained that his pursuit of success is about embracing the "duality" of high-stakes competition rather than individual accolades.
