Jaylen Brown records his 7th postseason (out of 9) with a negative on-off. He has achieved negative career on-off in both the regular season and postseason
The postseason is a very small sample size, much too small for on-off to be read into to a big degree, but it’s genuinely remarkable how the Celtics so consistently post a better net rating with him off the court.
He’s now posted a negative on-off in 7 of his 10 regular seasons, and 7 of his 9 postseason runs.
This signal has basically never been seen in an all nba caliber player for this period of time. There are one off seasons here and there, over the long term strong on-offs are a hallmark of the most impactful players in the league.
