do you honestly belive that Fish cant do even more Damadge to Rafa than Querry did????
Querry was good...but his BC. was preety low standard...Fish is taking the ball on BC. with confinece and IMO can hurt Rafa even more than Querry did
The problem is the style of game, Querrey isn't just an offensive player with a big serve, but he can play also some points fighting on the basline and also against an amazing player as Nadal you should do it, because you cannot play 3 hours of winners, that's crazy.
Mardy phisically isn't as Sam and imho he cannot do that, just try to play less blows to each point as possible and attack each ball, but as said Nadal is the best defensively and so I don't find really so much keys on this one.
