There are aspects of both I dislike. I’m not claiming they’re saints, to be sure. But what I like and respect about them outweighs what I dislike. (And, no, I’m not going to outline what I dislike about them, because that won’t do anything but further arguments.)
As
@don_fabio put it, when they play it’s a special occasion. We’re so lucky to be living in an era in which the two greatest men’s players of all time are contemporaries. People have endlessly discussed a theoretical match between Nadal and Borg. Or Federer and Borg. Or either of them vs. Laver. Unfortunately none of those matches will ever happen, but what has happened, and what continues to happen, are the top two meeting while in their prime.
You could even throw Djokovic into the mix, since it’s quite possible he will end up with more majors than Federer or Nadal. In a way, then, the three top players are contemporaries. Now, if there’s any player I absolutely loathe, it’s Novak. He rubbed me the wrong way right from the beginning, and it has only gone down from there. But, he’s also indisputably another all-time great, so I do respect his accomplishments, and often enjoy when he plays Rafa or Roger. In fact, some of the best matches I’ve ever seen have involved one of Fedal playing Novak. (Even worse: several of them have been when Novak won.) What I do, though, is pull back and look at the tennis objectively, and not focus on personalities, likes, dislikes, etc. In short, I enjoy living in this Golden Era of men’s tennis.
