I voted for Graf just because I had to but I want to ask:
why does anyone care?
What difference would it make if people thought Graf, Navratilova, Evert or Court was the GOAT? They played across very different eras, and it's painfully clear that not one of those was so much ahead of any other in regards to both achievements and influence on the game, especially that each one had a distinctive style with its flaws and advantages. This very fact makes all comparisons very subjective and almost arbitrary cause there are far too many variable factors to account for. And even if it's remotely possible to pick one, it's entirely meaningless. Should we start worshipping at her feet when the poll closes? It's taking the ideal of competition in sports a little far too much.
These are all greats of the game, and they just deserve to be celebrated as such.
Seriously though, we do it for the same reason we debate politics even though no politicians
ever accomplish anything...because we feel strongly about it. Certainly it's not
"entirely meaningless" -- as evidenced by the fact that you voted yourself.
As for my vote I'd say Martina = Greatest, Serena = Best. Martina knocked Chrissy off her
perch while she was still at her peak. Steffi didn't do that, and IMHO it would have happened
to her if Monica hadn't gotten hurt.
P.S. No more lurky, lurky!
