I love tennis, it's a great sport. Very difficult to play at a high level. You have to be a special athlete to make it into the top 100, let alone the top 10.
Men's tennis hasn't been the same for me since the retirements of Connors, McEnroe, and Agassi. However, we should appreciate the current era. Possibly the three greatest men's players of all time are currently playing when you consider the achievements of Djokovic, Nadal, and Federer.
On the women's side, Serena Williams and Monica Seles will probably always be my favorite players. It still bothers me that Seles' best years on the tennis court were robbed from her. Seles may have retired with more Grand Slams titles than any woman in history if she had not been stabbed by that deranged fan.
