I picked Myskina, Dementieva, & Davenport for sure.
I think Lindsay is just about @ the end of her career, she's come very close, but she is quickly running out of chances.
I have no clue what the future holds for Myskina, but I don't feel like she will win more slams, I think she's a good player, there are just too many that are better.
I don't think Dementieva will ever win one, unless her serve undergoes a major transformation. Its too hard to expect to be able to break your opponents serve everytime b/c u can't hold your own.
I thought Amelie, but the YEC was encouraging, perhaps there's still hope.
Kuznetsova has the ability to win the French IMO
Sharapova will win many more, Justine, Venus & Serena have more left in them as well.
Kim should win more.
