Are Dokic and Hantuchova as capable of winning slams as Sharapova and Kuznetsova?
Before winning the slams, Kuznetsova has a far worse records than Dokic and Hantuchova.
And Sharapova on grass is not nearly as good as Dokic on clay or Hantuchova on hardcourt.
Dokic has won 2 Tier I events before she turned 19 and Hantuchova won one of the biggest event on tour at 18. It's too bad they peaked at a year where Serena and Venus were at their peak and just about everyone else was out of contention in slams. Sharapova and Kuznetsova are lucky to have such a weak group of top 3 present for them to surprise everyone.
I think if Hantuchova and Dokic are at their peak this year, they could also have been slam winners.
