The future of Jaylen Brown has emerged as an early and compelling storyline of the Boston Celtics’ offseason, fueled by trade rumors and candid post-playoff commentary following the team’s first-round exit. While Brown has publicly expressed his desire to remain in Boston long-term, a looming contract decision this July could dramatically alter his trajectory with the franchise.
On May 6, Brown downplayed any notion of frustration in Boston in response to comments from Tracy McGrady. He emphasized his strong relationship with President of Basketball Operations Brad Stevens and his affinity for the city.
“I hate that our president of basketball operations even had to respond to this,” Brown said. “Me and Brad have a great relationship. I love Boston. And if it was up to me I could play in Boston for the next 10 years.”
Those remarks provide a fascinating backdrop to a significant choice facing the Celtics front office. Starting July 26, the team becomes eligible to offer Brown a two-year contract extension that would run through the 2030-31 season.
Brown is currently locked into three remaining years on the five-year, $304 million supermax extension he signed in July 2023. That deal, which runs through the 2028-29 season with no player options, carries the following salaries:
- 2026-27: $57.1 million
- 2027-28: $61 million
- 2028-29: $64.95 million
A maximum extension would add substantial new money on top of that foundation. Based on current salary cap projections, the two-year offer would look like this:
Extension Offer
- 2029-30 (age 33): $66.85 million (35% of the cap)
- 2030-31 (age 34): $72.2 million (36% of the cap) Total new money: $139 million
Handing out maximum extensions to players who still have three years remaining on existing deals remains relatively rare in today’s NBA. The Portland Trail Blazers did so with Damian Lillard in 2022 when he was 31—two years older than Brown is now—only to trade him to the Milwaukee Bucks a year later. The Bucks ultimately stretch-and-waived the final two seasons of that deal after Lillard suffered an Achilles tear. More recently, Devin Booker received a two-year, $145 million max extension from the Phoenix Suns last July at age 28, pushing his total commitment with the franchise to $316 million over five years.
Brown’s representatives will likely highlight Booker’s deal as precedent. After all, Brown has posted superior offensive numbers in recent seasons compared to the five-time All-Star and has long been regarded as the stronger defender of the two. Yet it would be surprising if Boston allowed another team’s decision to dictate its own plans for a core piece.
For Brad Stevens, who is no stranger to extensions, committing max money to a player entering his age-33 and age-34 seasons is far from automatic. Such a long-term investment could potentially diminish Brown’s trade value in the short term, even after a strong 2025-26 regular season. More importantly, there is little strategic urgency for the Celtics to act now beyond simply keeping Brown happy.
Stevens and the front office face more pressing roster and financial decisions in the immediate term. Extending Brown this summer would lock in significant future cap obligations without necessarily strengthening the team’s position for the present. For that reason, an extension does not appear to be among Boston’s top priorities as the offseason unfolds.
Whether the Celtics choose to extend Brown or hold off will send a clear signal about their vision for the franchise’s next chapter. One contract decision this summer has the potential to reshape not only Brown’s financial future, but his entire professional trajectory in Boston.
