A second thought. Have you ever thought that maybe Federer is that inconsistent or goes for too much because he can't keep up physically with guys younger than him? He knows it perfectly well and has it at the back of his mind that if he doesn't straight set them (or lose 1 set max) he just won't last in the end. Also, Federer doesn't have the privilege of playing on ultra fast surfaces like Sampras has in his day so he can't jus throw in a serve or two to get out of trouble, Fed has to WORK HIS A** OFF in every point to win it. I wanna see Sampras clutchness at 31 years of age. He couldn't even beat freaking Bastl at Wimbledon, let alone Djokovic or Nadal on these slow surfaces.
Just shows you how pointless H2H's are. Nadal beat Fed but in the end it meant jack, they both walked away with nothing. It's about winning titles.
