Celtics trade Jaylen Brown to 76ers as partnership with Jayson Tatum ends

Boston will meet the Philadelphia 76ers on Tuesday, marking the first game in which former teammates Jayson Tatum and Jaylen Brown play against each other after the Celtics completed Brown’s trade in early July. Sources familiar with the organization said the decision stemmed from a belief that the team could no longer sustain both players as primary salary-cap assets and that the on-court combination had lost its effectiveness following a first-round playoff exit in May 2025.

According to the sources, the Celtics had long positioned Tatum as the franchise’s cornerstone, signing him to a maximum contract in July 2024. Brown’s contract negotiations took longer, and his All-NBA status last season qualified him for a two-year, $142 million extension, which would have tied both stars to long-term, high-value deals. The front office reportedly concluded that maintaining both contracts would limit flexibility to improve the supporting roster.

Brown, a five-time All-Star, had expressed frustration in the past about perceived lack of respect and inconsistent playing time. He was also left off the 2024 Olympic team and was linked to several trade rumors before the July move. The Celtics reportedly informed Brown that they were shopping him, after which he submitted a list of preferred destinations; Philadelphia was not among them.

Former Celtics personnel offered differing perspectives on the relationship between the two players. Former assistant coach Evan Turner said he never observed personal animosity, noting that the teammates always greeted each other respectfully. Former captain Marcus Smart described the split as “a business decision” that unfortunately affected personal bonds.

Rockets coach Ime Udoka, who led Boston to the 2022 Finals, said the public nature of the split was unfortunate and emphasized that the issue was more about team dynamics than a personal feud.

The trade gives Boston financial flexibility and two first-round picks, while the 76ers acquire a player who helped lead the Celtics to a championship and a recent Eastern Conference Finals MVP award. The organization hopes the move will allow Tatum to remain the undisputed leader and enable the team to build a younger, cost-controlled supporting cast.

Brad Stevens, the Celtics’ president of basketball operations, faced a wave of online criticism after the trade, including threats directed at his personal accounts and family members.
