Re: "Every generation is better than the previous one. The game is always evolving"
then Stosur has also advanced the game by bringing ATP-style topspin into the game (and thus, advancing the game and bringing in something that hasn't been done before =/= being better, unless you consider Stosur to be better than Serena).
How do you advance/impact on the game by winning one slam?
You need to have had a significant time at the top for your game to be followed by others.
Do you think if Evert was a one slam wonder, there will be so many women playing with two-handed backhands?
