well yeah, he may not be that good his first year. But let's keep in mind, PG is the hardest position to grasp. Frosh point guards aren't just adjusting to more mature, physical players, but also a faster more complex offense which they are in charge of running. And White was doing that at a blue blood program in the premiere conference in college. And he was very successful.
Now he'll have to make another jump. But his ability allows him to be a force in transition game, but there is nothing that says he cannot learn how to manage his team with more experience in the half court. That he moves off ball shows he does have some feel for the flow, but he needs more reps.
