I'd say that on paper a player like this would definitely be one of the all time greats with a strong argument for being the greatest ever. He'd be in the running though, as would several other players. How much did the player impact professional tennis though? How influential was he in terms of affecting those that followed? These things are also factors in my view. To be one of the greatest players ever, with as many great tennis players as there has been, requires more than a large number of titles and records. The greatest players leave a mark that transcends the game and influences generations that follow them.
