Pretty much every tennis historian agrees that Borg was da man for far longer than 109 weeks. His actual reign was roughly double that, and while I've got
my issues with the Tennis Base rankings (or any ranking system, really) its 167 weeks for Borg is much closer to the mark:
https://en.wikipedia.org/wiki/World_number_1_ranked_male_tennis_players I converted years at #1 pre-1973 to weeks. 1 year = 52 weeks 1 year disputed by two players = 26 weeks 1 year disputed by three players = 17 weeks Here's an estimate of the all-time most weeks at #1: 1) William Renshaw...

That's why I say y'all should pay more attention to the YE rankings instead. Nobody gave a crap about the weekly #s until recently, and while the ATP/WTA has ironed out many of the kinks every tennis junkie understands that these "official" rankings are there not only to provide an accurate standing for the players but also to get 'em not to slack off during the yearly grind and to generate nonstop interest in the tour.
Which brings us to....
Right, you'd be hard-pressed to find a single pro who wouldn't swap all his Masters/500s/250s for an extra Slam. Ergo 21 > 20, 14, 11 or whatever, right?
Except that the Slam race itself is another modern phenomenon and historically the YE #1 ranking has been a more important barometer. That's where Bull falls short of his fellow GOATs. Going by total #s his 5 is good enough for membership (if on the weakish side a la Borg's), but not again when you look at the yearly distribution which shows his failure to defend his throne even once.
Now the obvious retort is that he had to deal with not one but two fellow GOATs at the same time, and it's undeniable that his competition has been heavier at the top than during Borg's, Pistol's or Fred's dominance. But what about Djoker, then? After all he defended his #1 ranking not once, not twice but
three separate times, no? What makes you think his great predecessors wouldn't have done just as well vs. a similar level of opposition, given Pete's and Fed's fast-court mastery or Borg's unrivaled kingship on clay and grass
and his stellar indoor resume unlike
Bull's? To try to explain this away by pointing to Fedovic is like
qualifying Rafa's relatively lackluster Wimbledon record with the same excuse: it might make sense for one or two outings, but not when we're talking his whole career when Murray of all people managed to sneak in a #1 season in '16.
Of course you could argue, just like I have granted on several occasions, that much of the tour is built for fast-court players and that makes Nadal's (or Borg's, for that matter) accomplishments even more impressive. But that's really a case for his longevity/(surface) versatility. Dominance is no doubt an important metric of GOATness and here Rafa does take a back seat to several of his peers.
