Any time a player loses possession before a shot attempt — through a bad pass, a steal, stepping out of bounds, or a shot clock violation. Turnovers are possessions handed to the opponent for free.
Possessions are finite and valuable. Every turnover is not just a missed scoring opportunity — it's a gift of one to the other team. Tracking turnovers separately from assists reveals how much a playmaker costs relative to what they produce.
High-usage players and playmakers will always have more turnovers — the question is whether their production justifies the cost.
In 2025–26, the best point guards in EuroLeague maintained assist-to-turnover ratios above 3:1 — Thomas Walkup led the league at 3.93, while Kostas Sloukas posted 3.92. Players who fall below 2:1 over a season are giving back a significant portion of their playmaking value. At the team level, Monaco embodied efficient ball security — averaging just 10.9 turnovers per game while dishing out a league-leading 20.7 assists, producing the league's best assist-to-turnover ratio at 1.90.
Players who attempt the most creative, high-reward passes will also throw more into traffic. A conservative player with 0.8 turnovers per game might simply be taking fewer risks — not making better decisions. Context and pass type matter more than the raw count.
A turnover in the backcourt with 20 seconds on the shot clock is a minor error. A turnover in transition that leads to an easy layup costs two points plus a possession. The box score treats them identically.
TOV = direct count from official scoresheet
Turnovers are recorded by official scorers and categorised by type: bad pass, ball handling, offensive foul, shot clock violation, out of bounds.
