He had started winning less after year 2007. In 2008 he won just one GS. In 2009 he won two (both thanks he could avoid Rafa). In 2010 he won just one.
So his drought didn't kick in at AO 2010. His drought kick in as early as after USO 2007. After that he could win any GS only when he didn't have to play Nadal and Djokovic (with an exception of USO 2008).
Isn't age of 26 too early for age related decline to kick in? Particularly more when you are doing physically fine enough to win two GS and 3 masters at the age of 36?
If you think objectively, it's not so difficult to find why most of the people believe that Fed's winning rate slowed down with emergence of big 3, not because age related decline.
wait, are we talking about the same djokovic who got his a** kicked by Tommy Haas ? he'd stop federer at wimbledon in 2009 ? LOL, ha ha ha

same goes for djokovic who lost to tsonga at AO 10 and then tsonga got destroyed in straight sets by federer.
Federer in his prime (2004-09) was 4-1 vs djokovic (only loss coming in AO 08 , when he was affected by mono, federer would've been slightly favored in AO 08, if not for that). Federer also beat Djokovic 3 times in a row from 2007-09 at the USO.
-------------
Federer was in better form than Nadal as well in AO 10 and would've beaten him (considering Murray was beating him even before the injury)
Wim 09 -- Nadal may not even have got to the final (facing a draw of Hewitt, Roddick, Murray).
A single match b/w federer nadal at Wimbledon alone, would be 50-50. If somehow Nadal got to the final with that draw, Nadal's chances would certainly be less than 50%.
RG 09, yes, federer got lucky in that he didn't have to beat Nadal, but Soderling beat him in 4 sets fair and square and FEderer beat him.
oh and of course Murray is excluded here from your bullsh*t because Federer kicked his a** in both USO 08 and AO 10.
Post #319 also exposes your BS.
