Because Federer is one of the best? Or are you saying last 2 years Federer is a peak Federer? So I guess Federer hit peak during 2004-07 then suddenly hit rock bottom (so amazing he still won few slams still!) and suddenly hit peak again in 2017-18 which coincidentally occurred when Novak-Murray and Stan were struggling with injuries. Any time when all players were in good physical conditions and matured as players should be ignored as Federer was distinct 3rd best in it, right?
Rock bottom is pretty strange way of describing it, the majority of tennis players though do win the bulk of their Slams in quick succession. I don’t think anyone who watch Federer post 2009 think he was anywhere near as physically good and clutch on the big point as he was before. This is when the bottle job against Djokovic at USO happened in 2010, losing to Tsonga in Wimby quarter and a slew of others like Berdych, Monfils, philonopoulos (or whoever his name is in Wimby 2013 first round) and so on. This is why downplaying one player at this or that point is pointless. Federer’s graceful style makes people think he’s timeless but he’s still human and there has been decline in multiple aspect of his game, mostly physical, ever since he hits 29/30 or so (most notably the speed and accuracy of his forehand), even if he gains on some other like the drop shot. Watch his hitting against Agassi in the USO final in 2005 and compare it with any other high profile match post 2009/10, it’s clear as day, and that decline works against him against the two best returner/baseliner of all time, even though he was still good enough to beat 95% of the field.
Anybody who has watched tennis also understands difference between Federer-Nadal h2h on grass and clay. Only one player of those across those 2 surfaces looked hopeless against his opposition. 6-1, 6-3, 6-0 in final ffs! That was worst loss in slam final in 2 decades or so back then and had happened to already anointed GOAT.
Well he lost to Luis Horna in the 1st round in 2003 and Kuerten in 3rd round in 2004 before going out to Nadal in 05. I’d never make the point that he’s anywhere near as good on Clay, and there’s only one way that can end with the Clay GOAT.
The H2H is useless because as already said, Clay is over-represented in the number, but that’s not the only reason. Even if they have played another 10 matches on grass with Federer winning the bulk of them, it’d still not matter, because it’s not reflective of their overall ability/achievement. Davydenko won a straight four matches against Nadal between 09-11 for example and lead the overall H2H, what do you make of that? Stylistic counter matters a lot and Federer couldn’t deal with Nadal’s top spin lefty forehand into his backhand for the majority of his career, until the change in racket in 2014. Is that a blemish against him? I guess you can say so, but teams/players having their boogeyman is nothing new.
