“You look at what Robert Williams does with the Celtics. They don’t really run plays for him,” Hill said. “He goes out there and is a defensive presence. He’s a presence on the boards and makes you change shots. If O can kind of figure out a couple of things like that, that will put him on the floor to have offensive opportunities. “We need someone like that to be an anchor in that second unit, especially with guys like Gallo, myself and Tony (Snell). If he can be that guy who comes in defensively, sets screens and rolls, he can definitely see the floor.”
