Groove Depp your List is well reasearched and Kudos for that
WTF are Rosewall,Tilden and Pacho Gonzales doing so much higher in that list.
They would really be Guinea Pigs for the Likes of Becker,Sampras,Agassi,Edberg,Nadal even Djokovic.
The only one to consider from that Era would be Laver who is really a GOAT contender along with Federer.
But Rosewall that much higher. I have seen his videos and he is Just About good.. Certainly not that much higher. That Era wasnt strong you have to consider that. tennis was just about evolving .
This is why such lists are truly impossible to perfectly come up with and are highly subjective. The game is totally different now than it was 40 years ago. Every decade that has gone by, talent means less and less. It has become more about cutting errors, having enough strength to be able to hit past your opponent and being physically talented. In a sense, it is a totally different game. You wouldn't see someone like Nadal in the 60s, nor would you see someone like Laver in the 2000s. So the only fair way to analyze these things are to compare each player to their own era rather than other eras and that is even a tough task as people can erroneously make meaningless stats/facts appear meaningful to blemish or improve a career. I mean even comparing 2000s and 1990s is tough enough, let alone 2000s vs the 60s, but I think this list is adequate for the most part.
