It's really interesting to see how Nadal's game and looks have changed in just these few years. Nadal at 17 playing Hewitt in the Aussie Open.
You hardly ever see Rafa use that really flat forehand anymore... How odd. It's extremely effective, though. The difference between his physical appearance then and now is, well, just astounding.
Yeah, that's why some people (including me) saying that he is underachieving on hardcourt. He is capable of more than just few masters titles here and there. So far he has been very disappointing at US Open and to some degree at AO.
