The argument is this: Federer is an all-time great, perhaps the greatest of all time; Nadal has a 13-6 career advantage over Federer. Now, someone who can beat such a man five times in seven Grand Slam finals has to be greater -- or at least equally great.
Maybe it's not fair to Nadal that those who bestow the title of the "greatest" on a player are aesthetes, as much as they are critics of the game. They're influenced as much by the beauty of a man's game as by his record in Grand Slams. And its beyond doubt that the beauty of Federer's game is greater than that of Nadal.
Nadal's game constitutes muscularity of body and mind -- in sport, these two attributes are rarely gifted in the highest degree to one man. But Nadal has them booth in the highest degree. He's both physically and mentally unbreakable. After that compelling semifinal victory over Fernando Verdasco, he had just one day of rest; Federer had two days to recover after the relatively easy win over Andy Roddick. Yet, in the final, it was Federer who ran out of breath and ideas in the fifth set. He seemed to be alive to the inevitability of his defeat. Such is the strength Nadal possesses, Federer was reduced to tears. After all, how much more can a man do than Federer did and still lose?
How much more Federer can do now? One year ago, he'd lost his Australian Open crown. Then in July, he lost the one title that seemed his by rights, Wimbledon. He was knocked out early at the Olympics. It seemed that the best of Federer was a thing of the past.
Yet, he somehow salvaged his year with the US Open crown. When he beat Juan Martin del Potro in the quarterfinals at the Australian Open, Federer played the kind of game that had seemed to have slipped out of his hand; he was masterful, and scary. The old Federer seemed to have returned.
Yet, on Sunday night, he was a forlorn, tearful man, having lost five matches in a row to Nadal. Federer has shown that it's dangerous to rule him out, so it's unsafe to make a prophecy. We must be content with saying that it'd be interesting to see what he can do now to get back at Nadal. It would seem that the 22-year-old Nadal can only improve -- he's actually improving, he's won Grand Slams on grass and hardcourt for the first time over the last eight months or so. It would be equally safe to say that we've seen the best of Federer, for no one's game can surely get better than he's displayed.
