DHJ Quick Take: Boston Celtics Land Mitchell Robinson on Three-Year Deal

Mitchell Robinson has agreed to a three-year, $47.4 million contract with the Boston Celtics that includes a player option in the third season, adding a proven rim protector and rebounder to a title contender.

  • How did Boston land Robinson? The Celtics used their spending flexibility to offer a deal the second-apron-limited Knicks could not match.
  • What does Robinson bring? He gives Boston elite offensive rebounding, interior defense, and lob-finishing in the paint.
  • Why does the signing matter? It shores up Boston’s frontcourt depth and rim protection as the team pushes to stay in contention.
  • What’s next? The deal becomes official once the NBA’s free agency moratorium lifts in the coming days.

The Boston Celtics have added frontcourt help, agreeing to terms with free agent center Mitchell Robinson on a three-year, $47.4 million contract, Dallas Hoops Journal has learned. The agreement includes a player option on the third season, which gives Robinson a path back to free agency in 2028 should he decline it.

Robinson arrives in Boston after spending his entire career to date with the New York Knicks, where he was a rotation fixture on the team that won the 2026 NBA championship. New York’s reluctance to cross into the second apron capped what the franchise could realistically offer, giving a contender with more spending room the opening to step in.

Mitchell Robinson Gives Boston Celtics Rim Protection and Rebounding

For Boston, the appeal is straightforward. Robinson ranks among the league’s most productive offensive rebounders and remains a disruptive presence at the rim, a lob-catching center who anchors the paint without needing the ball on offense. His limitations are just as familiar. He has never been a floor spacer, and his free-throw shooting has long been a liability that opponents can target in late-game situations.

On an annual basis, the contract lands in the range of the non-taxpayer mid-level exception, and the player option gives Robinson the flexibility to reassess after two seasons rather than committing to the full term.

Boston Celtics Avoid a Costlier Path to a Center

The signing also lets Boston sidestep a more complicated pursuit. The Celtics had generated interest in Detroit Pistons restricted free agent Jalen Duren, whose situation in Detroit has settled into a standoff.

Landing Duren would have required either an expensive sign-and-trade with the Pistons or an offer sheet that Detroit retained the right to match. By reaching a deal with Robinson instead, Boston solves its need at center outright and avoids tying up assets or cap flexibility in that process.

What Comes Next

Robinson fills one hole, but Boston’s summer is far from finished. The Celtics have been actively engaging rival teams on trade frameworks involving Jaylen Brown, and how that resolves will shape the rest of the roster.

The Robinson agreement itself cannot become official until the NBA’s free agency moratorium lifts in the coming days, though it at least addresses the team’s most pressing frontcourt need for now.
