No, I don't accept it as a reasonable view when you say that a man could be considered "the greatest" of both genders, but a woman could not, because of "absolute level". As discussed above, the same could be applied to Laver, and I've never heard anyone say it is reasonable to consider that he is not as great a player as ATP World #611 Wishaya Trongcharoenchaikul. Or, if you want to complain that I am exaggerating (I am, but it is to make a point), take Tomas Berdych. Surely his "absolute level" is much closer to that of Federer than that of ATP World #611 Wishaya Trongcharoenchaikul, so the argument would imply that both Tomas Berdych is a greater tennis player than both Serena Williams and Rod Laver.
No, I don't consider this a reasonable proposition. What is more, I don't believe that John McEnroe, or many of those who argue the point here, would agree that Tomas Berdych is a greater tennis player than Rod Laver.
In fact, McEnroe just put Serena above Novak Djokovic, and behind Federer, Nadal, Laver and Sampras, which is an implicit admission that the "absolute level" argument wasn't really that well thought through ...
