I'm still not sure why everyone is hating on Kournikova. So she was never the best female tennis player in the world. She was certainly top 10-20 for a while. That's quite an accomplishment. Of course, it's easy for people on the internet to belittle others when we don't have half the skill that they do at any given craft. Furthermore, as I already mentioned, Kournikova won plenty of doubles championships. If you're going to say that doesn't count -- well race car drivers have pit crews who can often make the difference in a race.
