just like there are multiple original souls who maintain arguments as of now that Federer isn't really goat, it won't be all that hard to come up with arguments in the scenario where someone else passes his slam count either.
nadal --> mucho mucho clay vulture, zero christmas exo, time at #1
djokovic --> would have racked up, what, 9 of his 21 slams in his 30s, in all likelihood at a much denser rate in his 30s than in what appeared to be his athletic prime where he had several consecutive one-slam seasons. In what is already starting to look like an unprecedented practical joke of an era w/r/t the under-30 gens, this career trajectory might end up making all 04-07 jokes pale by comparison.
there, the stock arguments are already made, ready for use. no end in sight for silly ttw wars about favorite male idols.
