​Joe Mazzulla recently reflected on Jaylen Brown’s impact, praising the former Celtics star who had long been synonymous with Boston’s green-and-white. Brown, who grew up in and around the city’s culture of basketball, spent about a decade with the Celtics and for a time carried the team with his dynamic play. In the 2025-26 season, Brown delivered a standout performance, averaging 28.7 points, 5.1 assists, and 6.9 rebounds per game—numbers that represented career highs or near-career bests. He steered Boston to the playoffs even with Jayson Tatum sidelined for much of the year, and his leadership and production felt integral to the team’s success. Yet the landscape shifted dramatically when Brown was traded to the Philadelphia 76ers in exchange for Paul George and a package of draft picks, signaling a new chapter for both franchises. Brown’s presence had been a defining element on the court, and his departure leaves a void that will be felt next season.
For Mazzulla, who rose from Celtics assistant to head coach, Brown’s influence remains a central part of his leadership reflection. “There’s an emotion that goes into it. There’s a processing pattern that goes into it,” Mazzulla said, citing how Brown pushed him and the team. “He made me a better coach, and I know that for a fact—the way he pushed me, the way he pushed himself, the way he pushed the locker room. He made me a better coach, and that’s what you focus on.” Brown’s resume with Boston is long and distinguished: five All-Star selections and two All-NBA nods during his time with the Celtics. The arrival of George in his place with Philadelphia added a new dynamic to the league’s landscape, and last season George contributed 17.3 points, 3.6 assists, and 5.3 rebounds over 37 games for the 76ers. The trade was perceived by some as a fracture in the Celtics’ era, but Mazzulla has remained focused on honoring Brown’s legacy rather than dwelling on what has changed.
“The part that I hope gets talked about more and the part I want to focus on the most is really just the respect, the appreciation, and the gratitude for what he did for the Celtics for 10 years,” Mazzulla told MassLive. “He’s a Celtic longer than I have been. He was here before me. He set the tone and started that and was a part of special things and continued that.” Mazzulla emphasized that Brown’s impact extended beyond statistics; it was about the culture, the inspiration, and the standard he established for teammates, coaches, and the organization as a whole. He underscored Brown’s role as a foundational figure who helped drive the Celtics’ sustained success.
As the Celtics move forward with a reshaped roster, fans and analysts will continue to reflect on Brown’s era in Boston—the moments of high-voltage scoring, tenacious defense, and the leadership that helped the franchise reach new heights. While Brown now wears the colors of another team, his influence on the Celtics’ mindset and Mazzulla’s own development as a coach remains a meaningful chapter in the franchise’s ongoing story.
