time when there was a greater disparity among the surfaces compared to when federer nadal and djokovic did iti can definitely say that the grass has changed dramatically but also the game has changed the reason why it was so difficult for me to win on grass wasnt because it was so fast i mean fast is ok the first one to hit a good shot wins the point somebody has a good serve it didnt matter if it was slow or fast pete aced me in paris just as many times as he aced me in new york or in wimbledon the problem was guys played coming forward so much they tore up the court through the middle and so by the end of the tournament im playing in the back of the court and every time the ball bounces its changing direction so the game changes guys are playing from the back of the court and bounces are truer you know so its a chicken and the egg i mean more predictable better quality the way they grow the grass it isnt quite as fast these are true statements but everybody has to adjust to it so i cant say my achievement is harder certain elements would be harder for me now too if im playing on grass against guys that can move as good as they move i mean grass is physical when you play long points on grass it hurts your body i dont know how i could have held up match after match having to play on grassbut while we all tend to gush at the accomplishments of federer nadal and djokovic three guys who hold the top 3 spots in the overall slam tally do you think people tend to overlook the factor of how the disparity among surfaces has reduced compared to your time or are we just talking about really special guys who wouldve been dominant in any erai had the privilege of playing all three of them novak was the worst of them because he was so young and it was an exhibition and he still beat me we had laver win two calendar grand slams 1962 69 on two surfaces grass and clay nobody has come close to winning four in the same year federer could have done that three times with one match against one guy that he couldnt seem to beat on clay nadal so youre talking about historic achievements i get it when my generation left andy roddick comes in as an american wins a slam somebody comes in and wins a slam but federer it looked like he was this guy coming in at the right time and then he ends up having to compete against two of the greatest ever for the rest of his career and does it so i feel like these guys just kept raising the bar of tennis while we can all live nostalgically itd be very unfair
