I've never seen him play, so I can't really speak to his potential. But one concern I do have is that he is supposed to be pretty much strictly a serve and volley player. Nobody on the tour plays this style any more for the simple reason that with today's strings it's so much easier to hit passing shots. I'm afraid that's going to limit his upside potential. Even in the best of circumstances, he'll probably suck bad on clay which will cost him a lot of ranking points.
