Projecting the Boston Celtics moves for the 2026 NBA offseason

May 16, 2026 - 13:10

The Boston Celtics are currently sitting pretty as defending champions, but the front office is already looking two years down the road. The 2026 NBA offseason looms as a major inflection point for a roster built on expensive, long-term contracts. The question isn't whether the team will make changes, but how drastic those changes will be.

One school of thought suggests minor moves around the margins. The core of Jayson Tatum, Jaylen Brown, and Kristaps Porzingis is locked in, but the supporting cast will need refreshing. Boston could use its limited draft capital to find a cheap, young wing or a backup big man who can spell Porzingis during the regular season. This approach keeps the championship window wide open while avoiding the luxury tax apocalypse.

The other path is far more aggressive. If the team underperforms or if the payroll becomes untenable, a bigger trade could be coming down the pike. Porzingis, with his injury history and hefty salary, is the most obvious candidate to be moved. A deal sending him out for a more durable center and a rotation player would reshape the team's identity. Even Jrue Holiday, who will be 36 by then, could become a trade chip if his production dips.

The Celtics' front office has shown it is not afraid to make hard choices. They traded Marcus Smart and let Grant Williams walk. In 2026, the luxury tax penalties will be severe, and the new CBA punishes teams that spend deep into the tax. Expect Boston to walk a tightrope: keeping its stars while finding cheaper, younger legs to fill out the bench. The 2026 offseason will reveal whether this dynasty has staying power or if the financial math forces a painful reset.
