I agree tangy. yes, Schuettler he's quick too, I forgot about him. and Roger... it's not that he's so fast, per se, but he moves so well that he gets to every ball.
Sorry, but I don't see speed as a weapon or a reason to believe a person will be a champion player. If speed were all it takes to be a champion you'd see little Ollie and Christophe Rochus atop the winner's podium a lot
