The defensive player, Patrick Beverley, places two hands, on the back of Tobias Harris, the offensive player with the ball. This is illegal, and a defensive foul is called. Note that a defender using two hands on an offensive player with the ball is an automatic foul, whether or not the offensive player’s speed, quickness, balance or rhythm is affected.”
