People tend to forget that women's tennis today is not as great as 10 years ago ( in terms of tennis). Raw power and error making would be intimidating to any of the past greats (even Steffi and Moncia), but it's not consistent power (like Seles and Graf) or accurate (like Seles) and will not last long (like Graf). None of the current group has plan B. Once Hingis is used to the power and realises that she will sometimes lose against the big hitters, she will be a force to reckon with. She only has to stick to her game a-b or c , she will have no problems in future. I can't belive I just said that, I don't even like her.
1997 was her year, but her main rival was severly injured that year, Hingis should have worked on her pshysical game then. She has a 2nd chance now, hopes she takes it and matures into a champion like a Navratilova, an Evert, a Graf, a Seles, and a nice person like Sabatini or Davenport.
