Is Henin an underachiever?
She obviously had a great career and absolutely destroyed the field in 07 but in my opinion henin in her prime is the best Player ever. she could have won 15+ slams like serena, graf or Martina.
she won "only" 3 slams off clay and lost a lot of finals.
of course her early retirement didn't help but in her first retirements Age graf had already won 20+ and I think henin was a better Player than graf was.
was she an underachiever, especially on hardcourt?
