If it becomes clear that there isn't enough spacing later on, Im sure they will just send Ball to the bench and JJ into the starting lineup. I do think people are expecting way too much from NAW though. With Ball, Jrue, JJ, Hart and Frank, I dont see him getting much playing time this year.
He runs an offense better than the other non ball and Jrue guards. So even though I think Hart, Jackson, Moore may be more ready to contribute. NAW will find playing time as 3rd string point guard.
