Who plays better on grass: Federer when he was 21 or Nadal today at 21? Federer in 2003 plowed through his draw only dropping one set. Nadal in 2007 dropped eight sets throughout the tournment. However, watching Nadal's shoot making, volleying and even his serve yesterday, I'm begining to believe that Nadal might have beaten a Federer of 5 years ago. Federer's serve back then did not have juice it does now and his backhand was even more vulnerable. Is it possible to think that Nadal, a so called one surface wonder, is playing as well as any 21 year old on grass? And based on that is it possible that Nadal, if he stays healthy (which is still a big if), could become not only an all-time great clay court player, but an all-time great grass player? It will be intersting to see how his career unfolds throughout the years.
