Two completely different styles of play, plus Nadal was always a much bigger draw than Djokovic. Djokovic is great but boring as hell, along with his arrogance he just wasn’t a crowd pleaser. No one could get people on their feet cheering like Rafa Nadal. He could make shots that just simply were not of this world. Many said Nadal’s body would not last ten years with his intense style of play. So far he has doubled that expectation and he will return.
Djokovic is the greatest returner who has ever lived. He is far from boring and not arrogant at all. He along with Nadal and Federer are among the most gracious and humble champions ever. If you want arrogance, look to the Williams sisters who seldom praise their opponents.
