Boston Celtics head coach Joe Mazzulla is reinforcing a philosophy of adaptability as his team builds momentum in the 2026 preseason. The Celtics are coming off a dominant 144-106 victory over the Philadelphia 76ers on October 10, following a 124-113 win against the Cleveland Cavaliers on October 8. Mazzulla, often linked to a three-point heavy 'Mazzulla Ball' style, argues his core principle is simply to get the best shot possible with the roster he has.
Many fans see Joe Mazzulla as the architect of a system defined by launching threes. But the Celtics coach says that's a misconception. His real focus is on maximizing possessions and finding high-quality shots, no matter where they come from. The specific tactics, he insists, are dictated entirely by the strengths of his current players.
"I think last year was a perfect example of that," Mazzulla told reporters. "We went in with a defensive system, thinking that was good, and we were the worst rebounding team in the history of basketball." He views nothing as fixed. A team's identity must evolve with its personnel.
For Mazzulla, roster turnover is just one part of the equation. Even if the exact same squad returned, each player would be different. Experiences over a summer, personal growth, and shifting dynamics mean a coach must rebuild team chemistry every single season.
"Their new relationship with me and Paul (George) is new, me and Mike (Conley), me and (Mitchell Robinson), so it's all of us," Mazzulla explained. He sees himself as an integral part of that chemistry-building process alongside the coaching staff and the entire organization. It's a collective effort, not a top-down directive.
The early returns on Boston's adaptable approach are positive, though these are just exhibition games. After securing a 124-113 road win over the Cleveland Cavaliers on October 8, the Celtics delivered an offensive explosion. They routed the Philadelphia 76ers 144-106 at home on October 10.
These preseason results offer a first glimpse at how new pieces might fit. The high scorelines demonstrate the pace and spacing Mazzulla values, but the real test is sustaining effectiveness when the games count.
Boston's final preseason tune-up comes quickly. They host the Charlotte Hornets at TD Garden on October 14. This game provides one more opportunity to experiment with rotations and sets before the regular season grind begins.
Mazzulla's comments make it clear that the work of defining this team's identity is ongoing. The 144-point outburst against Philadelphia is a data point, not a blueprint. As players like Paul George and Mike Conley integrate, the system will continue to shift. For Joe Mazzulla and the Celtics, embracing that change is the only way forward.
