Laver beat Rosewall in straight sets once to win RG, very impressive.
No denying that, his most impressive clay win for sure.
Laver was the best player in the world on clay atleast 2 other years, including the years Kodes won RG, but due to big money exhibitions which caused most players to skip RG didnt play. I think a player who was the best clay courter in the world 3 or 4 different years, is probably top 10 all time on clay.
Which years do you mean? 1971 may be debatable, as he won the Italian Open in that year, beating Kodes in the final, when the latter won RG.
I don't think you can give Laver more than 2 years as best on clay though. Which is maybe 1 more than Federer, and probably not enough to get him into the all time top 10 on clay.
These guys may all have greater clay credentials than Laver, for instance:
Wilding
Cochet
Nusslein
Trabert
Rosewall
Borg
Wilander
Lendl
Kuerten
Nadal
Djokovic of late is about the same in competitiveness vs Nadal on clay as hard courts, despite that Nadal is the better overall clay courter, and Djokovic the better overall hard courter. On outdoor hard courts he does worse vs Nadal lately if anything. Nadal's game has changed of late and some aspects of playing on hard courts helps him in the matchup despite the general surface preferences. I dont think unless Djokovic has a big run of form or Nadal some big loss in confidence prior to the U.S open that Nadal will lose should they play there this year either (considering Nadal's mental edge in the big match right now).
Not sure why you say this as Djokovic won 4 in a row against Nadal before the FO this year - I don't think Nadal has a mental edge over him on hard courts.
Surface doesnt matter nearly as much in that matchup as it does many of Nadal's others. And lets face it, without a RG title, Djokovic all time wouldnt have a remotedly high rank on clay, as much as I do think he is an excellent clay courter skill wise. So it would be silly to say just because Djokovic cant do something, someone else cant.
The point is that Djokovic has been a thorn in Nadal's side for many years, with a style of play which bothers him immensely across all surfaces (4 wins against him on clay since 2011), but when it comes to the biggest clay court tournament of them all, Nadal is always victorious. Nadal is aided by the larger space behind the court on Philippe Chatrier, and also has a psychological desire almost to prefer death to losing at RG (and no I'm not really exaggerating).
Federer in addition to not being the best clay courter has serious matchup issues with Nadal, but also developed psychological issues and underperformed in general. How do you explain how Nadal even has a winning record vs him on hard courts, and owns him something like 7-2 on outdoor hard courts, and no it is not just because they played some matches when Federer was old (30 or above say) since they played some when Nadal was 17-19 too. Federer in general has to take blame for his underperformance vs Nadal, even on clay, and one cant just assume everyone else would have done the same. The matchup issue with Nadal, which we cant guarantee Laver or whomever else having as we have no idea, well that is his problem to either solve or not solve, just as it doesnt matter one bit that on the flip side he was super lucky his main rivals besides Nadal like Roddick and Hewitt are ridiculously easy matchups for him.
Other than being a lefty, what advantage do you think Laver has over Federer, in terms of taking on Nadal at RG? I see nothing to suggest that Laver would have bested him.
I will concede Laver would have almost no hope of beating Nadal at RG in 2007, 2008, or 2010, but younger and non prime Nadal who Federer lost to at the French in 2005 and 2006, and the slowing down on clay Nadal of today? It certainly isnt impossible Laver would have won in some of those years, and possibly completed the Grand Slam with it.
The term is CYGS (Calendar Year Grand Slam).
Those who use the term 'Grand Slam' are living in the past.
Federer (the early years) and Djokovic (the later years) had chances in the matches some of those years (unless the middle peak years where they truly had none) but just werent mentally tough enough in the end; and there is no indication at all either of those are better clay courters than Laver. It doesnt mean it is an easy or anything but an extremely difficult task, but there is no evidence it is impossible for Laver to have managed.
I don't think either Fed or Djoker had chances to beat Nadal in any year except 2013, when I concede Djokovic was very close.
It's not impossible for Laver to have beaten Nadal, but it's highly improbable. I'm mainly basing this on the fact that Nadal has dominated Djokovic at the FO (6 wins, only once being taken to five sets), despite the fact that Djokovic has basically been Nadal's nightmare matchup for a number of years now, outside the FO.
If Nadal can dominate even those rivals who cause him severe problems at the FO, then there's no reason to think he couldn't have defeated the borderline all-time top 10 clay candidate Laver.
