I'm watching the Roddick-Enquivst match right now on the tennis channel. And it just seems like roddick is slicing the backhand more than ever, like someone mentioned earlier. What do you guys think is the root of the problem in roddick's backhand from a mechanical standpoint? To me, it seems like he hits the backhand very flat and doesn't come over the ball very well, which leaves him very little margin for error. In addition, his motion seems very forced and rigid. Is it too late for him to improve? I once read that Bill Tilden took an entire season or year just to work on his backhand....came back and became arguably the greatest player ever.
