Well CD, you can't deny that fast, low-bouncing courts favour Fed's game. Just look at the titles he's won in the last 2 years (counting since march 2010):
2010 World Tour Finals
2011 World Tour Finals
10 titles, 7 are indoors, the others on fast low-bouncing surfaces. He can go deep in tournaments with slow, high-bouncing courts, but he won't be the favourite to win against Rafa/Nole (especially against Rafa). His results in the past 2 years show what I mean...
of course his game is more ideally suited for slick low bouncing surfaces. take grass for instance. just look at how many wimbledon titles he has snatched there.
but he has shown that he can win on any surface.
i call that talent. and talent is what does it for him.
finally he is almost 31 now so he has to take what he can which has been my main point in this hread all along anyway.
you take what you can or you take damn near nothing. what would you do?
