2005 - beat peak puerta, peak federer
2006 - beat peak federer
2007 - beat djokovic, peak federer
2008 - thrashed peak verdasco, peak almagro, peak federer , peak djokovic
2009 - donation
2010 - just thrashed the field before him, here the argument that he did not beat anyone solid is vague because he was already a proven great by beating solid players in the previous years
2011 - took peak federer to clay school for the fifth time
2012 - welcome peak djokovic to roland garros finals with a solid 4 set hammering which would actually been straight set hammering but for the rain
Two remarks on my side..
From your list:
FED was at his peak between '05-'11 on clay...
An all time great performance in his own: So, to validate Rafa's results and validate his slams you need FED being at the peak..
In the meantime, FED at the peak was playing against clowns out of clay..
Strange among these clowns out of clay there was a guy, Rafa, who took 3 long years before winning a Slam out of clay..I mean, FED has been the 2nd best clay courter consistently, only to be beaten by the best clay courter. Can you say the same about Nadal on HC? [Nope, because as I said FED was there in plenty of events during his best years-'03-'07- waiting for Rafa in that surface]
Rafa won his first slam in 2005(RG). Since then, Federer has won 13 slams, Nadal has won 10. Who is the more dominant player [and I will not enter in the numbers of weeks as N#1 because is just too easy]?
If your answer to this is that "Rafa was still maturing on other surfaces" then dont call him Federer's rival. They are from different eras. The game is not about 2 players, its bigger than that. If players seeded 1 and 2 always met each other in the finals, other players wouldn't play the game. Its about overall dominance, not dominance on a particular player. And Rafa was less dominat than FED out of clay, i.e. FED was owning 2/3 of the season when Rafa was managing the 1/3 left!
As a conclusion: If FED has dominated his major competitors at his prime (which definitely ended around '08..From that moment on he was not so consistent and his best tennis is shown only at patches-as the current one- which last for some months and certainly no more for years
), this was not the sign of him facing clowns (if not the Rafa was one of them!), but just that FED is one of the great ever, a GOAT candidate, and the guy who mark his era. Namely. the following (always looking at the open era bit) classification of all time greats is still valid:
1960's - Laver (Rosewall an honourable mention)
1970's - Borg (Connors an honourable mention)
1980's - Lendl (McEnroe an honourable mention)
1990's - Sampras (Agassi an honorable mention..given after all his carrer GS)
2000's - Federer (Nadal an honourable mention)
All these amazing (all time) great players..Now, clearly, if it continue like that, having a FED able to win Slams even after his best years and at an age in which few players win ATP events...Well the guy is just proving over and over again to be the one who deserve the most the GOAT status.
