Obviously very high level trolling.
Why is it when you don't agree with something you resort to the "trolling" option?
Sampras' volleying was 10 times superior to Fed
LOL. Sure it wasn't 20 times better? Maybe 50 times better?
Federer's volleying is at another level on both sides.
Tell that to Edberg, McEnroe, Becker, Rafter or Pete, all of whom make Fed look like a junior at net. And I say that as a Fed fan!
I was comparing Sampras and Federer.
John Newcombe was a better volleyer on Grass than all the guys you mention.
They played after the grass was changed.
The changing of the speed of the grass at Wimbledon is a complete myth that continues to grow over the years.
The pace of the grass is a function of the wear and tear of the courts surface and the weather.
The modern baseline game leaves more of the court surface in good condition over the two weeks. You can easily see that by comparing photos of Centre Court on the Final Day in the 1970s and in the 2010s. Much more court wear in the 1970s because of a lot more serve and volleying that would cut up the parts of the court the ball would bounce on. This makes the ball stay low ... which gives the illusion that the ball is travelling faster.
The court curators tried to counter that by not cutting the grass surface as much. It is typically cut 2mm less these days than before 2000. All this does is allow the ball to bounce a little more consistently and a little higher. But it does not slow the pace of the court.
Also modern tennis racquets and strings, and evolution of stroke technique means the balls are travelling faster now than in the past.
So even if the court surface was slower, which it isn't, it would be more than compensated for by the use of modern equipment.
