NBA players have got to know that when they get a turnover or fast break rebound at the defensive end and bring it up court, very high likelyhood someone on the other team is gonna try to swipe the ball. LeBron may have gotten away with slipping and becoming bowling ball hits bowling pin. But it happened real fast and (i think) he knocked the ball loose before he took out Currys knees.
Fatass Parkers failure to secure the turnover by letting Chrissy Paul knock the ball away was another classic 2015 playoff turnover.
