The basketball star JJ Redick spoke during the US Open about Rafael Nadal, Roger Federer and Novak Djokovic's dominance. Redick said: "I appreciate greatness in any sport and like I said you are talking about the two of the greatest athletes ever, regardless of sport and the other thing with them is they have been able to sustain excellence well into their 30s, it's amazing, and this summer Rafa is 33, Roger and Serena are 38, so hopefully I am playing at a high level like them and in two or three years it's really remarkable what they have done and what I would say - I was having a conversation with a buddy of mine - it's remarkable to me that Federer, Nadal and Djokovic are all playing at the same time.
They are the three greatest players and they are all playing in the same era. Really in no other sport have you ever seen that before, you have not seen that in basketball surely, i mean LeBron James and Michael Jordan didn't cross paths at all.
So it's really rare to see that in tennis right now." On the loliness of a single sport, he added: "As a shooter in basketball you are spending a lot of time alone in a gym, it's a child alone in a backyard, alone in a park, working on your craft, doing something repetitively over, over and over again.
And that's how you build your skill set. When you get the competition, you have four other people on the court that I rely on. But there is nothing like tennis."
