Golden State Warriors: 47%
The Warriors’ problem for the majority of this past season was that their offense completely collapsed when Stephen Curry rested. Golden State scored just 104.2 points per 100 possessions when it was without both Curry and Jimmy Butler III, according to Cleaning the Glass. That figure ranked in the 5th percentile of all lineups leaguewide. For comparison, Golden State was up at 120.1 points per 100 possessions (85th percentile) with Curry.
However, Butler’s presence solved that problem after the trade deadline. The Warriors had a perfectly respectable 113.9 offensive rating when Butler took the floor without Curry, ranking in the 47th percentile. Average is just fine in those circumstances, because the Warriors are so great with Curry that they just need to hold serve without him. Add in phenomenal, 99th-percentile defense in those Butler-without-Curry minutes, and it’s easy to see why Golden State went 23-8 with the third-best net rating in the league after Butler first suited up.
Granted, the Warriors’ offense did fall apart in the second round of the playoffs when Curry was injured. But Butler was also banged up at the time.
