In basketball, a turnover occurs when a team loses possession of the ball to the opposing team before a player takes a shot at his team's basket. This can result from the ball being stolen, the player making mistakes such as stepping out of bounds, illegal screen, a double dribble, having a pass intercepted, throwing the ball out of bounds, three-second violaton a five-second violation, or committing an error such as traveling, a shot clock violation, palming, a backcourt violation, or committing an offensive foul. A technical foul against a team that is in possession of the ball is a blatant example of a turnover, because the opponent is awarded a free throw in addition to possession of the ball.
Some players are prone to turnovers because of having poor court vision[clarify] or making mental mistakes[clarify]. Also, many superstars average more turnovers than anybody on their team as they will often be handling the ball. It is unusual for the best player of a team to have zero turnovers. Also, a point guard may often have the most turnovers because they are usually the player that possesses the ball most for their respective team.
