More than 30 probably. There were only 3 players who came anywhere near (Murray, Wawrinka and Del Potro) and they were still a level below.
It's a good point though, it's not quite as simple as "he's won the most slams so he's the best". He might be, and there are other stats that you could use to make that argument aside from number slams. But it's not clear cut.
Djokovic has benefitted immensely from the demise of his rivals. Fair play to him for staying fit and healthy when they haven't been able to. And without COVID (albeit largely a problem of his own making mind) he'd have even more.
But he has been in effectively a one horse race for quite some time now.
Federer probably had that advantage for a few years towards the start of his career (particularly while Nadal was hopeless on anything other than clay).
Not sure Nadal ever has really, bar the odd tournament.
It's a bit like saying Smac is our best ever manager. He's certainly the most successful, but that doesn't necessarily mean he was the best.
Pitch Djokovic, Federer or Nadal against each other at their respective peaks and it's a brave man who'll confidently predict the winner.
Yeah, they could have got more, but both probably wore each other out to a degree, there was zero chance of letting off the gas in any sort of way.
I just think the tennis in the 2000's was a lot more competitive than the 2010's and much better than now. It wasn't just Fed and Nadal though, like you say, there was the ones you mention, plus Hewitt, Roddick, Safin etc, and any of those could probably win a few slams now. There were always wild cards in the top 30 though, who would go on a mad run for a season or so, they all came and went though, as they never got any real reward. I remember watching tennis a lot back then, used to bet on it, but out of touch a bit now I suppose.
Yeah, not having a dig at Djoko like, it must have been a nightmare for the years he was behind those two, most players would have gone downhill soon after as that must have been mentally tough, literally not being able to do any more. Fair play to him sticking that out, and he's got payback for that for over a decade.
Nadal was better than people give him credit for, especially during the time when Fed was top of his game. The problem was that on 3/4 of the surfaces he had to play against Fed, who was the best there's ever been on those, and was extremely consistent. Nadal also had a lot of injuries throughout his career, even when he was winning it was like there were always injury concerns.
Fed's the best for me, even at a time when the standard was very high, the tournaments other than RG were a foregone conclusion.
