Grass was much faster in the 90's. Why do you think there were so many serve and volley players at that time..
Oh come on. I started by pointing out how you had two premises that were highly confounded...now you're presenting a third. I have posted extensively about the lack of SV style players in the past, but rather than digress into a thorough exposition on why this is, let me simply help you by telling you, and any others who would subscribe to this theory,. that you should think about:
1.how long it takes to develop a pro player
2.how in the space of only a few years, with the retirement of Sampras/Becker/Edberg/Krajicek/Rafter etc. SV largely disappeared
3.whether potential pro players, and their coaches, design their games specifically for the speed of Wimbledon grass (do those that do, account for the majority?)
4.what happened to the SV on other surfaces? What about indoors?
5.despite Tim Henman's protestations, how come he was doing so well at the end of his career as an old man at Wimbledon?
6.do you actually believe there were just as many juniors and rookie pros playing SV style and that they were then selected against...due to failure at Wimbledon from slow grass? If you do, you're wrong on ALL counts, I assure you.
Whether you believe it has slowed down, or not, (and it certainly has not slowed down THAT much, despite what some players exaggerate, even scientific studies show that grass can only get SO "slow"). The lack of SV at Wimbledon, or in the game in general, is certainly not due to the slow grass conspiracy theory. I think that's absurd.
If one had great volleys, then in theory all they had to do was get to the net and win the point?.
Have no idea what this sentence means. In theory, if one had great volleys, one could win a lot of points if one got to the net with a good approach. Beyond that, great volleys mean nothing.
How do you measure a great volley, style, efficiency or with wins.
Any great stroke will have SOME correlation with winning, but there are so many confounds, such a relationship is IN NO WAY a good measure or predictor. Again, Leander Paes has great volleys, so does Reneberg, so does Woodforde, so does Flach, so does Annacone. It does not mean they are going to win WImbledon or be particularly successful. Too many other variables.
It's PARTICULARLY confounded when you point to Sampras 14 slams, (many of which were NOT from Wimbledon), many of which he largely won from the baseline, particularly in his younger years.
