A Comprehensive Look at the Boston Celtics’ Full 2025–26 Roster: Star Power, Offseason Moves, and Season Expectations.
The Boston Celtics enter the 2025–26 NBA season with a roster that reflects not just continuity and championship ambition, but also strategic upgrades, youthful promise, and the unmistakable drive to build a dynasty. After clinching the 2024–25 NBA title, the Celtics front office, led by President of Basketball Operations Brad Stevens, wasted no time in ensuring that the team would remain not only competitive, but dominant. From re-signing key stars to adding depth in critical areas, Boston has built a squad designed to maintain its edge in a fiercely competitive Eastern Conference.
At the heart of the Celtics’ roster remains the dynamic duo of Jayson Tatum and Jaylen Brown. Tatum, the team’s franchise cornerstone, is entering his ninth season with the Celtics. At just 27 years old, he has already established himself as one of the league’s most versatile forwards, a multiple-time All-Star, and a perennial MVP candidate. Tatum’s game has continued to evolve—his post play has improved, his court vision is sharper, and he’s become a more vocal leader both on and off the court. More importantly, Tatum has taken on the mantle of responsibility that comes with being the face of the franchise. His leadership throughout the previous championship run was instrumental, and the Celtics are betting heavily on him to continue that trajectory.
Jaylen Brown, who signed a massive extension in 2023, continues to be the perfect counterpart to Tatum. A two-way force with elite athleticism and a growing offensive arsenal, Brown’s presence gives the Celtics another All-NBA-caliber wing who can take over games when needed. The chemistry between Brown and Tatum, once questioned by critics, has matured into a balanced partnership that fuels the Celtics’ attack on both ends of the floor.
Anchoring the Celtics in the frontcourt is Kristaps Porziņģis, who has become a key pillar in Boston’s two-way strategy. After arriving in the 2023 offseason, Porziņģis found his rhythm with the Celtics and has been a reliable scorer, rim protector, and floor spacer. Despite concerns about his durability, Porziņģis delivered a strong performance in the playoffs last season, showing why his unique skill set makes him a matchup nightmare for most teams. His ability to stretch the floor from the five position opens up driving lanes for Boston’s wings and keeps opposing defenses guessing.
Joining Porziņģis in the frontcourt is veteran big man Al Horford, who, at 39, continues to defy Father Time. While Horford’s minutes are now more carefully managed, his impact remains massive—whether it’s through timely three-point shooting, elite defensive positioning, or invaluable locker-room leadership. Horford has accepted a reduced role gracefully, understanding his importance as a mentor and steadying force during high-pressure moments.
The Celtics also return their defensive anchor and emotional leader, Derrick White. After signing a contract extension last summer, White has blossomed into one of the most complete guards in the league. His defense is elite—capable of guarding multiple positions—and he consistently makes high-IQ plays on offense. White’s presence allows Boston to switch everything defensively and maintain a level of intensity that wears opponents down over four quarters.
Coming off the bench, the Celtics boast a strong rotation of contributors. One of the most important names here is Jrue Holiday, who opted into his player option for one more run with the team. Though now in his mid-30s, Holiday remains one of the most reliable two-way guards in the league. He may no longer need to carry a heavy scoring load, but his perimeter defense, ball-handling, and experience give Boston tremendous flexibility. Coach Joe Mazzulla often deploys Holiday in closing lineups, trusting his poise and ability to hit big shots in the clutch.
Payton Pritchard also returns, bringing with him the energy, shooting, and fearlessness that made him a fan favorite during the title run. Pritchard’s role as a backup point guard has steadily increased, and his ability to hit shots from deep and push the pace gives Boston a reliable weapon when the starters sit. He’s particularly useful in small-ball lineups where his tenacity and hustle can disrupt larger, slower opponents.
In the offseason, Boston made headlines with the addition of veteran power forward John Collins, signed via free agency. Collins brings athleticism, rebounding, and a scoring punch off the bench. His ability to run the floor, finish lobs, and defend multiple positions gives the Celtics more lineup flexibility, especially during games where Porziņģis or Horford rest. This move was praised across the league as a low-risk, high-reward acquisition that could pay dividends deep in the playoffs.
Another new face on the Celtics roster is rookie forward Jordan Walters, Boston’s 2025 first-round draft pick out of Michigan State. Known for his high motor, defensive grit, and unselfish style of play, Walters impressed during Summer League and is expected to earn rotation minutes as the season progresses. The Celtics view him as a developmental piece who fits their culture of hard work and team-first mentality. Walters may not be an immediate star, but his potential is promising, and he’ll benefit from learning behind Boston’s veteran core.
Sam Hauser continues to provide reliable three-point shooting and spot minutes off the bench. His ability to stretch the floor allows Boston to maintain offensive spacing, and his defensive improvement has made him more than just a specialist. Hauser’s role is expected to grow slightly this season, especially in games where floor spacing becomes essential.
Luke Kornet returns as Boston’s third big, offering rim protection and reliable minutes when Porziņģis or Horford sit. Kornet’s familiarity with the team’s system and unselfish approach make him a valued role player. He may not stuff the stat sheet, but his presence allows the Celtics to maintain their defensive schemes without a drop in effort.
Boston also retained Oshae Brissett and Neemias Queta, both of whom contributed sparingly last season but offer depth and hustle when called upon. Brissett’s athleticism and Queta’s size give the Celtics options in matchups that require added physicality or rebounding.
From a coaching perspective, Joe Mazzulla enters his third full season with a growing reputation for innovation, adaptability, and player development. Though initially under intense scrutiny when he took over the role, Mazzulla has won over fans, media, and players alike with his calm demeanor and emphasis on trust and accountability. His ability to manage egos, adjust in-game strategies, and prepare the team for playoff intensity was pivotal in last season’s championship run. Now, with a full complement of returning talent and new additions, Mazzulla has the luxury of working with one of the deepest and most balanced rosters in the league.
Boston’s front office has also made strides in developing a culture that attracts veterans who want to compete for a title. With Tatum and Brown as long-term cornerstones and a roster built around versatility, defense, and high basketball IQ, the Celtics have become a model for how to sustain success in the modern NBA. Their ability to blend homegrown talent, smart trades, and free-agent signings without compromising their core identity is a testament to their organizational discipline.
As the 2025–26 season tips off, expectations are sky-high. Anything short of another deep playoff run—or a repeat championship—will be seen as a disappointment. Yet, the Celtics seem more than capable of meeting that challenge. Their roster is stacked with talent, experience, and chemistry. They’ve built a team that can adapt to any style of play, dominate on defense, and execute in crunch time.
This version of the Boston Celtics is not just aiming to win—they’re aiming to leave a legacy. With a balanced roster, strong leadership, and a hungry fan base behind them, the Celtics are poised to make another serious run at NBA glory. The 2025–26 roster reflects a franchise that knows who it is, what it wants, and exactly how to go about getting it.
