The Boston Celtics are heading into the 2025-26 NBA season under intense scrutiny and facing a crucial period of transition. After celebrating a championship in 2024, the franchise encountered a stunning reversal in the 2025 playoffs, falling short of expectations.
A severe Achilles injury to cornerstone forward Jayson Tatum has further complicated the season ahead. With financial challenges and significant roster adjustments underway, the team must recalibrate, refocus, and find a new balance.
2024 NBA Championship and 2025 Playoff Disappointment
The Boston Celtics entered the 2025 playoffs as the defending NBA champions, having triumphed in 2024 after a dominant season that solidified their legacy. However, the euphoria was short-lived.
Despite returning a largely intact core, the team underperformed when it mattered most. Their early exit from the 2025 postseason shocked fans and analysts alike. The lack of offensive cohesion and a noticeable dip in defensive intensity raised red flags. The once-celebrated championship roster looked vulnerable, a reality that prompted significant organizational decisions just weeks later.
Jayson Tatum’s Achilles Injury
The biggest blow came with the news of Jayson Tatum’s Achilles injury. The All-NBA forward suffered a severe rupture that is expected to sideline him for the majority—if not the entirety—of the 2025-26 season.
Tatum has been the Celtics’ offensive engine and emotional leader, and his absence will be impossible to ignore. With averages hovering around 27 points per game, his production, leadership, and two-way presence created equilibrium for Boston’s lineup. Now, the team must move forward without their franchise cornerstone.
Jrue Holiday Traded to Portland
Financial pressure and future planning drove the Celtics to trade veteran guard Jrue Holiday to the Portland Trail Blazers. In return, Boston acquired Anfernee Simons. While Holiday brought championship experience, elite defense, and leadership, his departure helped the Celtics reduce their luxury tax liabilities.
Simons offers a different profile—a younger, offensively dynamic guard known for his scoring bursts and three-point shooting. The move signals a tactical shift toward youth and offensive firepower, reshaping the backcourt heading into the new season.
Luke Kornet Leaves for San Antonio
Backup center Luke Kornet signed with the San Antonio Spurs during free agency, leaving a void in Boston’s big-man rotation. Kornet’s contributions weren’t flashy, but his rim protection, floor spacing, and reliability off the bench were essential over the past two seasons.
With Tatum injured and the roster already thin in the frontcourt, Kornet’s exit further complicated Boston’s depth at center. His departure created the need for a new interior presence to support the team through a transitional year.
Luka Garza’s Iowa Pedigree Brings Promise to Boston’s Frontcourt
In response to losing Kornet, the Celtics secured free agent center Luka Garza on a two-year deal. Garza, known for his physicality, rebounding, and high-effort play, brings a fresh element to Boston’s interior game.
Although he has yet to make a consistent impact at the NBA level, his potential and hustle could earn him a defined role. Boston hopes he’ll provide the toughness and presence needed to reinforce their frontcourt in the absence of Tatum and Kornet.
Luka Garza’s arrival in Boston is more than a roster fill—it’s a calculated bet on one of college basketball’s most decorated big men. A former University of Iowa standout and two-time National Player of the Year, Garza left a legacy of interior dominance, footwork mastery, and relentless work ethic.
His college résumé was built on back-to-the-basket scoring, a soft touch around the rim, and sheer physicality, all traits the Celtics are banking on translating to the pro level during a pivotal transitional season.
Early summer workouts and preseason scrimmages have already turned heads. Garza has impressed coaches and teammates with his conditioning, intensity, and ability to finish through contact. His post moves remain as polished as ever, and his understanding of floor spacing fits well within Boston’s offense. With Tatum sidelined and Kornet gone, Garza’s role could expand quicker than initially expected, offering critical support in the paint.
Fans have already drawn nostalgic comparisons to past Iowa greats, most notably B.J. Armstrong. While their games differ in position and style, the work ethic and leadership echoes through the generations. Boston hopes that Garza’s collegiate pedigree will inject both toughness and efficiency into a frontcourt in need of identity.

Jaylen Brown’s Expanded Role
With Tatum sidelined, Jaylen Brown is set to become the primary option on both ends of the floor. Brown, who recently signed a five-year supermax contract worth $304 million, is now under pressure to lead. His performances will shape the Celtics’ success this season.
Known for his athleticism, defensive tenacity, and ability to score from multiple levels, Brown must evolve into a vocal leader while sustaining All-Star production. His response to this increased responsibility could define the Celtics’ short-term direction.
Derrick White’s Importance Grows
Derrick White, already a respected presence in Boston, will take on a more significant role with both Tatum and Holiday gone. His basketball IQ, perimeter defense, and unselfish playstyle make him a critical piece.
White is expected to facilitate the offense, mentor younger players, and handle more defensive assignments. His consistency will be crucial, especially in clutch moments. As the team’s second-most experienced guard, his performance will either stabilize or unravel Boston’s backcourt balance.
Payton Pritchard’s Opportunity
Payton Pritchard has shown flashes of brilliance but has often been buried in the rotation behind veteran guards.
Now, he has a legitimate opportunity to log major minutes and prove he belongs in the league’s upper tier of reserve guards. His 3-point shooting, scrappy defense, and energy could serve as catalysts for Boston’s second unit. With Holiday gone and a changing roster, this season might be Pritchard’s defining chapter in a Celtics uniform.
Amari Williams Set for Development
Amari Williams, the Celtics’ recent draft pick, was initially expected to develop gradually. However, injuries and roster shifts have changed the equation. The team now sees Williams as a potential contributor this season.
With size, mobility, and defensive instincts, Williams offers a high-upside profile. If he adapts quickly to the NBA’s pace, he could carve out a niche as a rotational big, especially during stretches when Garza or other frontcourt options face matchup challenges.
Embracing a Transitional Season
The Celtics are openly embracing 2025-26 as a transitional season. Without Tatum and facing a retooled roster, the emphasis will be on growth, development, and positioning for the future.
Management is betting on internal improvement and lineup experimentation rather than short-term results. Younger players will receive more playing time, while veterans like Brown and White carry leadership responsibilities. The front office views this year as a stepping stone—painful, perhaps, but necessary for sustained success.
