The Boston Celtics traded Jaylen Brown — the 2024 NBA Finals MVP and a player who finished sixth in the 2026 regular-season MVP vote — to the Philadelphia 76ers for Paul George, a 2028 first-round pick, a 2031 unprotected first-round pick, a 2028 second-round pick, and a 2030 second-round pick. The deal became official on July 6. [1] Brown said publicly there was a "lack of respect" from the Celtics organization. Brad Stevens, the Celtics' president of basketball operations, said the trade was necessary.

Stevens did not say it was about basketball. He said it was about the collective bargaining agreement. Brown and Jayson Tatum together, Stevens explained, would have consumed approximately 70 percent of the salary cap under the NBA's new CBA — a concentration that makes championship construction impossible at that cost level. [1] That is not a roster decision. That is the NBA's new labor architecture doing exactly what it was designed to do.

The CBA's steeper luxury-tax aprons, negotiated in 2023 and in full effect from the 2025-26 season, impose hard spending limits that restrict teams well above the salary cap from acquiring players via trade or free agency. [2] A team carrying Brown-and-Tatum at their projected extensions would have been functionally frozen: unable to add the supporting pieces a championship team requires, and facing annual luxury-tax bills that ownership may not sustain indefinitely. The apron mechanism does not prevent a team from being good. It prevents a team from being built.

The Sixers get Brown alongside Tyrese Maxey and Joel Embiid — a trio that Boston's own coach identified as potentially the most dangerous offensive unit in the Eastern Conference. [1] Boston gets George, 36, whose best seasons are behind him, plus four draft picks whose value depends on how quickly the rebuild proceeds. The financial logic for Boston is defensible. The basketball logic is harder.

The story Brown told in a Twitch livestream after the trade was announced was not about basketball logic. He said he never asked to leave Boston. He never requested a trade. The Sixers — who eliminated the Celtics in the first round of the 2026 playoffs — came back with offers repeatedly until the Celtics accepted. [2] That sequence, in which the NBA's own salary architecture created the conditions for Boston to trade a player who didn't want to leave, is the story the CBA's architects intended: championships break up because building them is too expensive to sustain.

Stevens's candidness about the mechanism is unusual and worth preserving on the record. General managers routinely describe trades in terms of basketball fit and long-term development. Stevens named the CBA by its function and acknowledged publicly that it set the ceiling. [1] The ceiling held.
