Any time a player loses the ball before a shot goes up, through a bad pass, a steal, stepping out, or the shot clock. A turnover is a possession handed to the other team for nothing.
The pack lands around 1.0. This season's leaders are out on their own:
Possessions are limited and valuable. A turnover is not only a missed chance to score, it is a free one given away. Counting turnovers next to assists shows what a playmaker costs against what he creates.
TOV = counted from the official scoresheet
Turnovers are logged by type: bad pass, ball handling, offensive foul, shot clock, out of bounds.
TOV: Turnovers / AST: Assists / AST/TOV: Assist-to-Turnover Ratio
The players who try the hardest passes will also throw more away. A player with 0.8 turnovers a game may just be taking fewer risks, not making better reads. What kind of pass it was matters more than the count.
A turnover in the backcourt with 20 seconds left is a small mistake. A turnover in transition that becomes a layup costs two points and a possession. The box score treats them the same.
In 2025–26 the safest playmakers kept their assist-to-turnover ratio near four to one. Kostas Sloukas led the league at 3.92 for Panathinaikos, with Thomas Walkup just behind at 3.80 for Olympiacos, both living above five assists a game on barely more than one turnover. At the other end, high-usage scorers like Kendrick Nunn gave the ball away 2.9 times a night. Neither is simply better. One is asked to create, the other to keep it safe.
A turnover is losing possession to the other team before getting a shot off, through a bad pass, a steal, a travel or an offensive foul.
TO stands for turnovers. Lower is better. High-usage playmakers naturally record more because they handle the ball most.
Raw turnovers punish players who handle the ball a lot, so compare them to how much a player creates. Assist-to-turnover ratio and turnover percentage put the number in context.
