Re: "Every generation is better than the previous one. The game is always evolving"
Second statement is true, first isn't...whatever era you're born into, you play whoever is your competition across the net. And really, the further apart 2 players are in time, the more difficult it is to compare them. It really just becomes subjective eventually, how much each person gives weight to certain factors such as competition, tour size, training. etc. will vary.
That being said, I think Serena is a greater player than Margaret Court ever was
And not just because Court's a crotchety old homophobe...
