Many experts point to the year-round schedule, the constant pounding on hard courts, & the mental grind as factors that make professional tennis so taxing. Even at the ripe old age of 27, some are even writing off the mighty Federer, thinking that he has possibly lost a step.
From an all-around sports fan's perspective, this is kind of peculiar to me in a sense. It's obvious that a tennis player's career is much shorter than the avg. pro athlete. However, there are so many great athletes that dominated their sport late in their careers. Examples that come to mind (Zidane, Michael Jordan, Carl Lewis, Steve Nash, Jerry Rice). Agassi is really the only guy in the past 10 years or so that has come close to being the best at an older age. He's obviously a guy that was extremely fit physically. And you can't discount his attacking style of play, which possibly saved his legs some pounding.
My question to the fans on this board: Could a 30 yr old dominate tennis? If so, what would it take (i.e. traininig, scheduling, physique, mental toughness, etc)? For those who don't think it's possible, I'd also love to hear your thoughts!
