Is it possible for other players to play exactly the same way as Nadal even if they try really hard? For example, does Federer have the ability to continuously run down balls and make maximum effort for each and every point like Nadal does, even if he really wants to? Why is it that no player in the world could replicate Nadal's playing style with equal success? Are they all very lazy to do so? I wish there are more tennis players in the world with Nadal like attitude and approach towards the game.
