But you argument is that tennis hasnt been the same standard every decade so what does arguing winning in multiple decades advocate for your argument?you are just wrong. serena has won in ever decade she has played in so your point is mute. serena has had deeper fields. evert has said as much. henin was only a thing because serena wasn't on her game.
it isn't a niche, it is understanding the history of the game.
I am a fan of Serena and we (you and me) generally see eye to eye but i dont agree with the first post i quoted from you.
