I would say that men's tennis is primarily ruled by the Eropeans pretty much since 04' ish. Americans haven't really had much success with Roddick, but now have many younger players in the top 200. Players like Harrison, Young and Sock have already had fairly decent starts to their careers. But I just don't imagine any of those 3 winning a slam. One exception may be Denis Kudla who is 18 and ranked 185. I would like to learn more about him and see some more matches of his in the future. Another thing is maybe the American coaches are just not as good. I used to get the feeling that American players were just a serve and FH. Is the European teaching system better than the American way?
