Fed isn't really a serve and volleyer. so he can't do very well at the net. but if Fed always stays at the baseline, he can't beat Nadal on clay either. Nadal has the highest percentage of shots at the baseline on clay. How can Fed beat him? So either Fed stays at the baseline and lose to Nadal in all finals, or try to beat him at the net. It is a sure thing to lose to Nadal at the baseline, but it is risky at the net, so at least the risk is shared by Fed and Nadal when Fed is at the net. So personally I don't think Roche's strategy failed. It is that Fed can't execute it well, or he is not the type of player to execute it well. If this is true, then Fed is destined to be beaten by Nadal on clay in his entire career. Or maybe this is true. Fed tried S&V and lost to Roddick in Koon Yoong. Look that is Roddick! not Nadal! Nadal certainly can hit passing shots better than Roddick from the baseline. so I think Fed still has to mix up his game more, attacking the net on opportunity and finish it at the net. He probably can't play a pure baseline or a pure S&V game. I think Fed and Tony had some arguments in the strategy against Nadal, not that Fed completely think Tony is wrong. But Fed has had doubt ever since IW, so they parted ways.
