Boston Celtics. 13. team. 18. . 11-10. Previous: 11th

As detailed in a recent Nylon Calculus piece, the Celtics are suffering from major regression almost across the board from their key players. Of those, the disappearing shooting from Jaylen Brown might be the biggest problem. His athleticism and defensive versatility are key for Boston but if he’s a non-threat on offense it’s hard to find a balance — maintaining their defense has hamstrung their offense.

Brown is shooting less than 30 percent on open and wide-open 3-pointers and if he had simply been making those shots at the same rate he did last season, the Celtics would have scored roughly an additional 33 points this season, enough to push their offensive efficiency from 27th in the league to 23rd.
