The six worst teams in the NBA this season had one thing in common: all scored less than 112 points per 100 possessions. (The only team in that range to make the playoffs was the Magic, thanks to their second-best defense.) Your Brooklyn Nets had the third worst offense in the league, scoring just 108.1 points per 100 possessions. It’s safe to say that their quest for “sustainable success” will have to begin with figuring out how to score.
The only near-absolute requirement for a good offense is good shooting. Across the league, teams’ offensive efficiency was very strongly related to their true-shooting percentage, a weighted combination of FG%, 3P%, and FT%.
