I think it's a little of both. He is not being used to his strengths. A lot of this is personnel, and has a chance to be rectified with some moves. In addition, Fox is a young, YOUNG PG just beginning to find his way at the top level of competition. For example, you can see when he pushes he is still adjusting to trying to use his speed with NBA hands swiping at the ball. This is often how he turns it over, many times bringing his dribble so low while moving so fast, he loses it. We need time, and we have plenty of that with Fox.
