Anyone notice that Monfils, Fish and Dodig had very good success playing serve and volley and attacking the net against Djoko and Nadal on summer hardcourts? I personally think some pros need to attack the net more. I believe Federer would have beaten Tsonga at Wimby if he had attacked in 4th and 5th sets. I don't buy into the rackets and strings make it impossible to attack. I think the pros don't use the tactic enough to be successful at it. Federer is the only top 10 guy who has potential to be a great volleyer and even he does not use attacking play enough. What do you think? Is the best change against Djoko and Nadal to mix in a fair amount of S/V and net rushes?
