LAST SUMMER, AFTER the Boston Celtics celebrated their championship with a parade, confetti, cigars, and trophy photos, it was time to focus on the future. On Monday morning, July 1, just 10 days after the celebration, team governor Wyc Grousbeck made a surprising announcement: his family was selling the controlling interest in the franchise.
Despite this major development, the Celtics, boasting prime-age talent, chose continuity. They kept their championship roster together, pushing forward with the goal of repeating and securing an unprecedented 19th banner. They achieved a 61-win regular season and swept through the first playoff round in five games. The plan remained to win the championship first, and then address the business matters after a potential second parade.
However, the Celtics unexpectedly face a critical Game 3 on Saturday afternoon at Madison Square Garden, stunningly trailing the New York Knicks 2-0 in their conference semifinal series. If the Celtics cannot turn their performance around in this series, particularly overcoming an ill-timed shooting slump that saw them miss a remarkable 75 three-pointers in the first two games while blowing back-to-back 20-point second-half leads, their continued viability as a core group will suddenly come into question.
Regardless of this season`s outcome, the future for this championship-winning Celtics roster was already uncertain due to the immense cost of keeping the team intact, a roster expertly assembled by team president Brad Stevens.
The Team Sale and Financial Implications
THE CELTICS ARE being sold to a group led by investor Bill Chisholm at a valuation exceeding $6 billion. This record-breaking transaction was seen as a positive sign for the health of the NBA. Chisholm, a longtime Celtics fan and Massachusetts native, has reportedly been gathering a coalition to finance this enormous purchase.
Once the sale is finalized, it is clear that the Celtics, last sold for significantly less than $400 million over two decades ago, will have a substantially larger financial burden to manage.
Securing the Core and the Looming Tax Wall
The Celtics understood that their present and future were intrinsically linked to their star wings, Jayson Tatum and Jaylen Brown. They prioritized locking these two players into long-term contracts, a plan successfully executed. Brown signed his extension in 2023, followed by Tatum in 2024, securing their presence with the team until the end of the decade at a combined cost exceeding $600 million.
For at least three years, since the new collective bargaining agreement between team owners and the players` association began taking shape, the Celtics identified 2025 as a critical financial point. We are now just weeks away from that moment, irrespective of the playoff outcome, as Tatum`s new contract takes effect, and the Celtics are set to become a “repeater” luxury tax payer.
Among the current core, veteran big man Al Horford is the only pending free agent, in the final year of his contract. Sources indicate he intends to continue playing and would like to return. Every other key player, including guards Derrick White and Jrue Holiday (who both signed extensions in 2024), center Kristaps Porzingis, and Sixth Man of the Year Payton Pritchard, remains under contract for the future.
Under normal circumstances, maintaining a great assembled team would be lauded as smart management, and Stevens` front office has done just that. However, the current NBA landscape presents financial complexities that even expert roster construction struggles to overcome.
The Staggering $500 Million Figure
AND THAT`S WHERE the enormous number emerges. Projected for the past year, it remains staggering and historically high. According to ESPN front office insider Bobby Marks, even if Horford does not re-sign, the Celtics are projected to face a payroll, including luxury taxes, of $464 million next season. If they keep their first-round draft pick, which they likely need for an inexpensive contract, and fill out the rest of the roster with minimum salaries, the team payroll could surpass the $500 million mark.
Last season, the Celtics achieved record revenue, fueled by their championship run and four rounds of home playoff games. Losing Game 4 in Dallas last year, despite holding a 3-0 lead, proved financially beneficial as they clinched the title at home with a lucrative Finals game. This helped boost the franchise`s revenue to roughly $450 million, as reported by Sportico.
One does not need a finance degree to grasp the developing mathematical problem. This looming financial storm has largely been kept separate during the current season. Multiple sources confirm that the team has not discussed potential future spending changes with player agents, a deliberate strategy to keep the focus solely on performance.
The Celtics players` families maintain strong bonds, fostered through deep playoff runs and consistent roster composition since the COVID-19 pandemic. Stevens and his staff have successfully shielded the players from concerns about ownership uncertainty, allowing them to concentrate on winning another championship, according to those close to the team.
Consequences of a Playoff Exit
Earlier this season, NBA teams received positive news when the league significantly increased its debt limit from $275 million to $425 million per team, thanks to new 11-year, $77 billion media rights deals set to begin next fall. This provides a cushion for teams if they choose to absorb losses. In February, Fitch Ratings upgraded the NBA`s credit rating from `A-minus` to `A`, suggesting league owners are financially stable overall.
However, if the Celtics fail to advance past this second-round series against the Knicks—and thus fail to defend their title, following the pattern of the past five NBA champions—the extent of the repercussions is uncertain. Expensive financial consultants aren`t needed to advise against spending $500 million on a roster that didn`t even reach the conference finals.
While this financial reality shouldn`t be on the minds of the Celtics players during the series, the league-wide discussion about the existential threat facing this team will undeniably intensify with each loss. This potential financial impact represents a far more serious consequence than how a loss might affect individual players` or coaches` reputations, legacies, or other typical narratives that emerge in the NBA ecosystem each spring.
