The Boston Celtics were regarded as championship contenders this year, hoping to become the first team to repeat as NBA champions since the 1968-69 Celtics, until they struggled to beat the New York Knicks in the playoffs.
Their hopes were massively dented after Jayson Tatum’s heartbreaking Achilles injury in Game 4. He had to undergo major surgery after the setback, which turned out to be successful, fortunately.
Now, NBA insider Shams Charania has revealed what could be the possible reason for the sudden roster upheaval that followed.
Shams Charania Reveals the Impact of Jayson Tatum’s Injury on Celtics’ Plans
The Celtics’ core remained intact until recent days, when Jrue Holiday was traded to the Portland Trail Blazers for Anfernee Simons and two second-round picks. Kristaps Porziņģis was also traded to the Atlanta Hawks in a three-team deal, with Boston receiving Georges Niang and a second-round pick while Brooklyn acquired Terance Mann and the Hawks’ No. 22 pick.
These moves were largely motivated by financial necessity, as Boston faces a projected payroll and luxury tax bill exceeding $500 million for next season – which would be an NBA record. The franchise was already operating in the NBA’s punitive second luxury tax apron, which comes with severe roster-building restrictions.
During a recent appearance on the Pat McAfee Show, Charania explained that Tatum’s injury has impacted the Celtics’ plans for the future.
“What’s come of Jayson Tatum potentially missing all of next season is this uncertainty around Boston. And that’s allowed other teams to really start preparing to go after players,” he said.

I am told Al Horford has a pretty robust free agent market outside of Boston” ~ @ShamsCharania #PMSLive https://t.co/q6sRoUQklm pic.twitter.com/tv5cIoSpfM

The uncertainty Charania referenced stems from a harsh financial reality. With Tatum’s $54.1 million salary still counting against the cap despite his injury, the Celtics face what would be the largest payroll and luxury tax bill in NBA history. This has transformed what should have been a championship pursuit into what Charania described as a “retooling year” rather than a complete rebuild.
Charania also mentioned that teams have been making offers to land Jaylen Brown in a trade, which is honestly surprising considering his expensive supermax contract worth approximately $285 million guaranteed. However, Charania noted that while teams are “throwing crazy offers” for both Brown and Derrick White, it would take “a pretty insurmountable package” for Boston to part with either core piece.
The Celtics appear to be threading a delicate needle – cutting costs while maintaining enough talent to remain competitive during Tatum’s recovery and preserve their championship window for his return.
Al Horford Drawing Significant Interest
In addition, the ESPN insider claims that Al Horford has a ‘robust’ free agent market, where we can expect some major moves in the coming days. The 39-year-old veteran’s potential departure would be symbolic of the franchise’s shift in priorities.
Horford, who was originally expected to return for another championship run, now faces a decision between staying with a team in transition or pursuing another title opportunity elsewhere. Teams are certainly expected to go after the experience and veteran leadership he provides, particularly contenders seeking playoff-tested depth.
With that said, the Celtics have already saved a huge amount on luxury tax penalties and successfully moved below the dreaded second apron through their recent trades. The moves represent more than just cost-cutting – they signal a strategic pivot from win-now mode to positioning for Tatum’s return in 2026-27.
It looks like Tatum’s injury has pushed them to an awkward spot where Boston now has to balance competing priorities: remaining competitive enough to justify Jaylen Brown’s massive contract while avoiding the crippling financial penalties that could hamstring their future flexibility.
It would be safe to claim that Tatum remains the cornerstone around whom this franchise will rebuild, but the next 12-18 months will test whether Brad Stevens can successfully navigate this transitional period.
The goal appears to be preserving the championship window rather than slamming it shut, but that delicate balance will require continued roster moves and difficult decisions about which pieces fit the retooling timeline.
