What happened: Jayson Tatum addressed the Jaylen Brown trade at the 2026 ESPY Awards, calling the split "weird" after nine seasons as teammates. The Celtics traded Brown to the Philadelphia 76ers on July 6 for Paul George and four future draft picks.

Why it matters: Philadelphia now pairs Brown with Joel Embiid, Tyrese Maxey and Vj Edgecombe, and the 76ers remain in the mix for LeBron James in free agency. Boston, coming off a first-round playoff exit to Philadelphia last season, enters the 2026-27 offseason retooling around George instead of the running mate Tatum had played alongside since 2017.
