If the French Open is the hardest to win, then the GOAT MUST have a significant achievement in that category. I am no Laver fan -- heck, he was before my time and the only reason I pay attention to him is because Martina Navratilova says he was her hero-- but it seems that if you assume that, then the GOAT must have something there.
