It worked in that Sampras won Wimbledon seven times, but he never won the French Open. And Federer only won the French once, when he didn't have to face Nadal in the tournament. Most impressive IMO was Wawrinka's win in the French over Djokovic. (And I should note that Wawrinka appears to have a lot of brute strength in his right arm.) The backhand was IMO the weak part of Pete's game. Of course his serve was monstrous, overhead was monstrous, net game was good, court movement was off the charts, running forehand incredible. His running forehand provided a lot of cover for the backhand. And as a serve and volley player, he didn't need the backhand as much as other players.
