That combined with clearly the highest level play even considering the era she plays in (excluding clay), already the most longevity of any women player in history, having no losing or equal head to heads vs any key rivals which isnt true of any other great in history, and dominating by far the toughest womens field in history in the 99-2003 period, is more than enough.
King,Evert,Court,Navratilova.That is longevity.
