“This is an example of a free throw violation committed by a defensive player positioned along the lane line. The defensive player, Kawhi Leonard, who is positioned along the lane line, enters the key before the free throw is released. Because the free throw attempt was unsuccessful, the offended team is awarded another free throw attempt. Had the free throw been made, play would continue without penalty. During free throw attempts, defensive players positioned along the lane lines may not enter the key, nor vacate their lane space by more than three feet, until after the ball is released by the shooter.”
