When asked to evaluate the greatest tennis players in history, John McEnroe frequently splits his analysis across different court surfaces, designating Rafael Nadal as the undisputed greatest clay-court player of all time for his fourteen French Open titles, Roger Federer as the epitome of grass-court elegance and mastery, and Novak Djokovic as the greatest hard-court player and statistical overall standard-bearer. McEnroe has frequently emphasized that Djokovic's unmatched record of twenty-four Grand Slam singles titles, combined with his remarkable versatility and ability to win multiple times across every major surface, places him at the very forefront of the historic men's tennis GOAT conversation.
