Roddick will be outside the top 10 this time next year if he carries on like this. His serve was unreadable 2 years ago. Now almost everyone can read it. His forehand is not so accurate and he still needs to learn how to volley. He's too one dimensional. Ginepri lost US Open junior finals to him - pure power that's why (look at Chardy now - he's the same), but he's worked hard and is looking good. Blake has overcome many physical probs and in my mind has the best game out of the lot of them (save AA). He's class (and half British so it's a suprise!).
I wouldn't be suprised if Roddick never won a slam again.
