From his most recent results, it appears that Federer is not dominating like he has in previous years. He actually had a losing record against top 10 players last year, which is really surprising to me. I think the mono illness really played a big role in his lack of preparation & confidence overall. I think this year he'll definitely have a more consistent year. I found a quote by Giles Simon quite interesting: "I don't think (Federer) can improve his game now, but I think he's a very, very good player - maybe the best player of history," Simon said. "It's going to be difficult for him to improve again, but I think he can maintain his level." So what you guys think? Federer's game was so close to perfection (at his best), it is probably difficult to imagine him improving much, if any. However, I do find it interesting. Especially when you see athletes in other sports peaking at much later ages. If I were to look at professional basketball, many & most of the best players are 27yrs plus: Kobe Bryant, Paul Pierce, etc. Often you see a guy like Kobe slim down a bit as he gets older, perhaps push himself in the gym more. I suppose with the constant travel, in tennis this is difficult. I know that Agassi later in his career focused heavily on off-court training often skipping tournaments in favor of hitting the gym. Perhaps Federer would be well-served to take a similar approach.
