Well, it surely looks like no one can really challenge Federer-Nadal finals but who could be the dangerous floaters this FO ? I mean some guys who can spoil this whole rivarly things ? Let's see the Nadal's half There's Ivo Kalovic if he reaches R-16 and serves out of his mind.. Of course, there's Almagro and Blake. Hrbaty is always dangerous. Also Stepanek because of S&V style How about Federer's half. I don't see any one in his quarter maybe except Ancic? Gasquet is very dangerous of course if he advances further to meet Federer. Moya is after all FO champion. I somehow think Gaudio can be dangerous but he has to reach semi-final to meet #1 seed.
