Steal %
The percentage of opponent possessions that end in a steal while a player or team is on the floor — measuring active ball-hawking ability.
Raw steal totals reward players who play more minutes and teams with more possessions. STL% normalises for both, asking: of every 100 possessions the opponent has, how many end with the ball being taken? It's a cleaner measure of defensive activity in the passing lanes, and it captures something DEF RTG alone doesn't: the ability to generate turnovers rather than just preventing scores.
Benchmarks
- League average: ~8–9%
- Good: above 9.5%
- Elite: above 10.5%
In 2025–26, Paris Basketball led available EuroLeague data with 9.3% STL%, followed by Barcelona and Partizan around 9.6–9.7%. Teams below 8% are passive defensively and rely on shot contests rather than ball pressure.
Paris Basketball's 9.3% STL% in 2025–26 ranked among the highest in available EuroLeague data — they forced a steal on nearly one in ten opponent possessions. This aggressive style is a double-edged sword: disrupting passing lanes creates transition opportunities, but gambling for steals can leave gaps in defensive rotations. Paris finished 15–23, suggesting their high-risk defensive style generated turnovers and excitement, but not enough stops overall to translate into wins.
Tensions
Teams that gamble for steals can be beaten easily when those gambles fail — a defender out of position gives up a layup. High STL% teams sometimes have surprising weaknesses in their DEF RTG because their aggressive approach creates open shots when it doesn't work. Steals are high-reward, high-risk.
Guards and wings dominate steal leaderboards because they're in the passing lanes more often. Centers, who protect the rim, will almost always have lower STL% regardless of their defensive quality. Never compare STL% across positions without acknowledging the structural difference.
Formula
STL% = Steals / Opponent Possessions × 100
STL%: Steal Percentage / STL: Steals / Poss: Possessions
