If one were to judge the Greatest of All Time debate, at least for the time being, solely on the basis of statistical achievements, primarily the highly sought-after Grand Slam titles in tennis.
With 24 Grand Slam victories, Novak Djokovic dominates his two most formidable opponents, Rafael Nadal (22) and Roger Federer (20).
In fact, Djokovic’s Grand Slam total is probably going to rise because he is skilled on all three surfaces—clay, hard, and grass. The significant drop in men’s tennis quality over the past few years is the elephant in the room.
Before him, Federer faced the best of a dying generation in competition. Grand Slam champions Andre Agassi, Marat Safin, and Pete Sampras were among them. Among their fierce peers were Grand Slam champions and frequent finalists Andy Roddick, Carlos Moya, Juan Carlos Ferrero, and Lleyton Hewitt. And he easily overcame the best players of the new generation, including Andy Murray, Stan Wawrinka, Marin Cilic, Juan Martin del Potro, Djokovic, and Rafael Nadal.
