The following is the rankings list that Matt Cronin contributed to the Tennis Channel for its current top 100 greatest players ever, (male and female combined), five-part series. Here is the the Tenis Channel’s final rankings, which is an average of the contributions by various experts. Here is mine. It’s important to note that this list was written nearly a year ago, before Novak Djokovic won three more Grand Slam titles. In a list written today, he would be in my top 40, at least. I did take into account doubles contributions, but to me this is primarily a list of great singles players, so I weighed singles more heavily.
