Roddick obviously has an amazing forehand and serve. With an exception of his net game, his backhand is probably is most glaring weakness. Compared to other top pros....he doesn't really seem to stroke his backhand...his arms seem very stiff and straight. I wonder how much better roddick could be if he learned to hit a backhand like a safin or agassi. I definitely think he'd have a better chance against federer.
