How exactly do we measure greatness? By the number of titles? The number of Grand Slams? Maybe. But not only. There are certain things that numbers can't convey. Numbers won't show that this man plays tennis more beautifully than anyone before, or that he is the all-time most revered athlete in the world for his grace and elegance on and off the court. From here on, whatever the scoreboard says, his legend can only grow. In time, Roger Federer's legacy will prove more perpetual than any number.
