What happened: Brad Stevens tied the Brown move to depth and role flexibility for 2026-27. The deal ended nine seasons of the Tatum-Brown partnership in Boston.
Why it matters: Boston opens 2026-27 without its longtime second star, shifting creation load to Tatum. Open wing minutes and closing possessions now decide the Celtics rotation balance.
By the numbers: Tatum and Brown played nine seasons together in Boston.
What to watch: Camp will reveal who takes Brown's minutes and late-game assignments.
