No a large part of it is old age, Fed is ancient in tennis terms. Wait a minute here, didn't you claim Novak winning 8 more slams or something is more likely than Fed getting to #2 spot before FO. No, what Federer showed that even in his old age far removed from his peak he can still kick ***. I hope he wins another slam just to shatter your little world even further. Not at all, he needs to improve tremendously in that regard in order to match Nadal.
