http://www.youtube.com/watch?v=v_cNQs6e0kw&feature=related Notice alot of things interesting - Roddicks first serve is way more consistent now His second serve was way more aggressive in 03 Roddick's forehand despite being more aggressive, has way more variety now, although much less of a weapon. His backhand is alot better now. Perhaps the most glaring, Rod is a much better returner now than he used to be. He still is horrible at approach shots, however volleying is underrated. Fed serve's better now, however he is very streaky. He swung with alot of racquet speed in 03. Backhand is about the same tbh. Fed moves about the same now, MAYBE slightly better. Slice is used way more than topspin drive on backhand now. And of course, both of their service motions have changed substantially.
