I'm not downplaying anyone's success. They are all very good tennis players. Nadal is probably the clay GOAT. Federer is a legit contender for overall GOAT. Djokovic is a very good multi-slam champion.
I don't think it detracts from their ability to point out the obvious fact that their dominance is assisted by the nature of the modern tour.
Nadal is not probably but he is clay GOAT......it's not a debate even..........Federer is the best ever and GOAT in a sense that he holds 90% of stats and records in tennis history plus is A game is better than anyone's ever.......and Novak is a great multi slam champion.......the fact that you dont have mugs winning Slams today proves this is a very good modern tour.....no Chang's here man
