The Celtics have a net rating of +4.7 when Jaylen Brown is on the court in 1537 mins, and are +13.6 in 727 mins when he’s off it. In contrast, they’re +10.9 in 1601 mins with Derrick White on and -0.8 in 663 mins with him off
The Celtics have pretty much been better without Jaylen Brown on the court for almost his entire career, so you can’t really point at the noise that comes with on/off within a singular season.
Payton Pritchard’s production and efficiency this season is a lot better with JB off the court (463 minutes, 1235 minutes he shares the court with him). Per 75 possessions, his usage rate jumps from 18.4% to 28.0% (+9.6), points per game jumps from 16.4 to 29.2 (+12.8), assists per game jumps from 5.4 to 8.1 (+2.7), rebounds per game jumps from 4.7 to 5.1 (+0.4), true shooting% jumps from 55.2% to 61.6% (+6.4), free throws attempted doubles from 1.8 to 3.6 (+1.8), three point percentage increases from 33.1% to 41.2% (8.1) and his +/- jumps from 2.4 to 9.2 (+6.8).
Low leverage removed by the way.
