Yeah Nadal is a great player even outside of clay but having 2/3rds of your slams on one surface (except the days 3 of 4 majors were on grass which is a different thing) is pretty much unheard of. It isn't versatile enough compared to the other greats.
In my view, Nadal is if anything underrated - and there's a strong bias against him on this forum from the predominantly pro-Federer fanbase
Shall we examine his versatility (or lack of) in a bit more depth to put in perspective?
Off clay, Nadal has won
6 majors - 4 on hard courts, 2 on grass. How does that stack up against other all time greats?
Connors off of his favourite hard courts has 5
Borg off of his favourite clay has 5
McEnroe has the same number of hard court majors - and he's a GOAT candidate on the surface
Lendl, sans clay, has 5
Edberg has the same number of Wimbledons - and 2 fewer finals
Becker and Edberg put together have just 1 more hard Slam (and 1 less final)
Agassi outside his favourite hard courts has 2
Where's the problem here? Nadal compares favourably with most ATGs, subtracting players' favourite surface or Slam... and a lot of those guys have gaping holes in their resume - that Nadal doesn't
It seems to me Nadal is held to the standard of his clay court prowess. That's an
impossible standard for anyone on any surface to match. He's also held to the standard set by Federer and Djokovic on grass and hard courts - and obviously falls short.... but so do they on clay to him (and by a
much wider margin)
I don't think anyone sane argues Nadal is the best grass or hard courter of his time - clearly he trails his two top rivals.... but I do think he's done enough on those surfaces to justify being top notch player on them (and he's done so having to go through those two rivals - GOAT candidates on the surfaces in question)
Nadal- a controversial pick maybe, but people forget how ridiculously clay heavy his record is when evaluating his greatness
Now lets look at his dominance on clay
Clay has historically been the hardest surface to master - or maintain mastery over. Lots and lots of one shot wonders at the French Open... far more than at Wimbledon or on the hard courts
Borg's record of 6 titles at the French was considered
safe as a bank, virtually impossible to match. The closest anyone got to it was half way... I believe only 1 player so little as reached 6 semi-finals, let alone finals - and sure as hell forget about titles
Nadal has all but doubled it.
He has doubled what was considered an impossible mark!
What was the previous record for Masters level equivalent titles on clay? 7 or 8, I think. Nadal has
quadrupled it!
Nadal's quality on clay is so mindboggling that I think we struggle to take it in. To paraphrase an attributed quote,
"1 French Open is a great achievement, 11 is a statistic"
If he's that good on clay... great for him, say I
He has won more majors on clay than All time greats Connors, McEnroe, Lendl, Wilander, Edberg, Becker, Agassi, Sampras, Federer and Djokovic
put together
Why hold it against him, since he's doing just fine on the other surfaces (dual domination of which is fairly common)?
