Coming off their 2024 NBA Finals victory, the Boston Celtics were well-positioned to defend their title and dominate the league once again, not only for the 2024–25 season, but for the next several years. After essentially retaining their entire roster, spearheaded by superstars Jayson Tatum and Jaylen Brown with a supporting cast that was second to none, it seemed no other team in the NBA had the collection of talent, continuity and experience to dethrone the Celtics.
But things can change quickly in the NBA. In the blink of an eye, the hopes of Celtics fans vanished.
In the third game of the 2025 Eastern Conference semifinals against the New York Knicks, Tatum tore his Achilles tendon diving for a loose ball. It was a gut-wrenching sight that no fan, player or coach ever wants to witness.
Achilles injuries typically sideline a player for nearly a full year, as treatment is handled with extreme care due to the severity. The Celtics are expected to be without their best player for the upcoming season, dramatically altering expectations for another NBA title run.
Team management viewed Tatum’s injury as an opportunity to reset the team’s financial situation, trading away expensive contracts like those of Kristaps Porziņģis and Jrue Holiday, both of whom were key contributors to the 2024 championship run. Additionally, the team parted ways with veteran Al Horford, who is reportedly not expected to re-sign with Boston.
These moves suggest the Celtics are shifting toward long-term planning and moving away from the all-in approach that defined the past few seasons. For fans accustomed to a championship-or-bust mentality, this change has understandably caused some unease. While the Celtics’ ceiling may be lower this season, it presents a chance to improve around the margins and revitalize the roster for Tatum’s eventual return.
Jaylen Brown is an All-Star capable of leading a team on any given night — most notably during the 2024 season finals when he won the series MVP — and a Tatum-less rotation gives him the chance to truly assume the role of the number one option for an entire season. Many have labeled Brown as merely a secondary piece: someone whose skills primarily complement Tatum, but who is not suitable for leading an offense. Now, for the first time in his career, Brown will have the keys to be the team’s Batman rather than Robin.
If Brown can prove himself as a true primary scorer in Tatum’s absence, the Celtics will enter the future with two legitimate number one scoring options, making them an even bigger threat when Tatum returns from injury.
Another player with a chance to take a big leap forward is Payton Pritchard. Last season, Pritchard earned a larger role in the rotation as a dynamic spark off the bench. With increased minutes, he won the NBA’s Sixth Man of the Year Award, given to the league’s best bench player.
Given the current roster situation, Pritchard could be inserted into the starting lineup to provide some needed scoring punch. Throughout his career, he has consistently seized opportunities when given more playing time. Now, with starter-level minutes, Pritchard could be poised to take another step forward and continue his steady upward trajectory.
Beyond giving players the chance to grow and showcase their true talent, this season also presents a pivotal opportunity for head coach Joe Mazzulla. Chris Gasper of The Boston Globe described this year as a “prove-it” season for the Celtics’ head coach.
“We’ll learn just how good a coach Mazzulla is when, for the first time as Boston bench boss, he’s not dealing with a ready-out-of-the-box championship contender,” Gasper wrote in an article published in August.
While it’s clear Mazzulla deserves to be recognized as one of the NBA’s top coaches, the upcoming season offers a real opportunity to prove just how capable he is in leading, managing and elevating a team. With a roster lacking its usual star power and depth, Mazzulla will need to be as dialed in to coaching as ever, and silence skeptics who argue his success has been more about the talent he inherited than his ability on the sidelines.
He also faces the challenge of re-energizing a team that many have already counted out. With new faces in the locker room and returning players being asked to take on bigger roles, Mazzulla will need to be a stabilizing presence and adapt his coaching approach. How he manages these dynamics will be one of the most compelling storylines of the season.
While some Celtics fans may feel pessimistic heading into the upcoming season, there is still plenty to be excited about. The path to success is rarely straightforward, and it is often seasons like this that lay the foundation for future championships.
If things go well, this could be a formative year for both the players and coaching staff. It has the potential to strengthen the team’s core, sharpen its supporting pieces and set the foundation for long-term success once Tatum returns.
