The Wilson NBA DRV training markers are a coaching aid that’ll guide players through many different drills in order to develop proper footwork, court awareness and enhance the movement with a basketball. The markers do not compromise the freedom of motion, and they generate a loud and consistent sound to signal the correct movement. There are five numbered markers – each featuring a pebbled base to prevent slipping on the court surface, plus a drawstring net is supplied with them to ensure comfortable storage after practice.
