I was watching some of the Fed Sampras Wimbledon match and I was just thinking he served particularly well that match, great placement, good variety. I think this was partly out of necessity. In the marathon Wimbledon final against Roddick when racked up that insane amount of aces I kind of think he really needed to have those free points because there where times when Roddick seemed to have Fed on the ropes. This lead me think, if Fed had played in the 90s I think his serve would be better just as result of him going for it more. I'm not suggesting it would be as good as Goran's or Sampras's but It would have been better than the serve he's had most of his career. I'm not suggesting Fed isn't already great server as it stands now but I think he would have been an even better server if he would have played in the 90's out of sheer necessity and there have been a few matches which have shown he's up to the task. Just like volleying, if he did it more he would be better at it. He wouldn't become Edberg but he would be better than he is now. I suspect that as Fed gets older his serve will actually improve even though the rest of his game will be in decline simply because he will be forced to rely on it more. I think whenever Fed's last year on the tour is, it will be interesting to see if he keeps his current playing style or if he will become more aggressive and go for big bombs off the serve and forehand. Thoughts?
