Basketball: The Truth About Stealing

Steals matter. But how much? Ben Morris at Fivethirtyeight.com transformed steals into the most underrated box score stat. "Steals have considerable intrinsic value. Not only do they kill an opponent’s possession, but a team’s ensuing possession — the one that started with the steal — often leads to fast-break scoring opportunities."



The crux of the argument relates to how much generating steals translates to overall game impact (similar to Butterfly Effect). I think the author means that steals are a more nuanced form of contribution that are hard to replace. Understanding that correlation is not causation, steals reflect athleticism and anticipation, but their precise value is unknown. Obviously, imprudent gambling for steals backfires with out of position defense and better scoring chances. 



The Celtics led the NBA in defensive efficiency but were near the bottom in steals. If you want to beat the Warriors, you better find a way to reduce their possessions, as they led the NBA in FG percentage (50.3%), 3 point percentage (39.1%), and free throw percentage (81.5%). They did have the fifth most turnovers per game at 15.4

Can we teach stealing? Good defense sets up steal opportunities. 



1. Core concepts like the "Helpside 'I'" load the defense to the ball. You might call that "defensive numbers." 



2. Recognize high opportunity steal situations. The "wing to top" pass may be the most frequently stolen pass in basketball.

3. When the ballhandler turns her back to the help defense, they may have a chance for unexpected doubling or theft. 

4. Defenders can "bait" (lying in the weeds) offense into throwing passes to the wing by appearing casual yet being ready to spring to the ball.

5. "Time the crossover." Anticipate the crossover and look to deflect it as the ball returns to the dribbler.



6. "Pull the chair." Savvy defenders getting 'backed down' can force turnovers or steals by releasing defensive pressure, 'pulling the chair.'

Kawhi ask why? 




Kawhi Leonard prefers to get the steal as the ball leaves the dribbler's hand. 




"Thou shalt not steal gamble." Gambling on defense can create high quality scoring chances for offense. 

Opportunistic defense earns you more minutes. Use your head and athleticism, offensive weakness, and errors to force more steals and turnovers.
