Jaylen Brown vs. advanced stats: Making sense of his previous on-court impact with Celts

An analytical deep dive examines the divide between Jaylen Brown's traditional star box score numbers and his skeptical advanced on/off metrics following his summer trade from the Boston Celtics to the Philadelphia 76ers. Despite finishing sixth in MVP voting in 2026, Boston posted better net ratings with Brown off the court in seven of his ten seasons there.

Front offices increasingly rely on regularized adjusted plus-minus (RAPM) data, which analysts argue limited Brown's trade market across the league. In return for Brown, the Celtics acquired veteran forward Paul George and draft picks, while Brown has posted a positive on/off differential through his first ten games in Philadelphia.
