I want greatest doubles players, not teams. So, it will be like this: Would you consider Navratilova a better doubles player than Shriver? Would you consider Zvereva a better doubles player than Fernandez? Would you consider Hingis a better doubles player than Novotna or Sanchez-Vicario. I guess what I am asking is what player(s) would've had equal success with another partner had the one they had great success with never played (e.g. Navratilova/Shriver, Zvereva/Fernandez). I am only asking for Open era because the results were more carefully recorded. So, how would you rank: Navratilova, Hingis, King, Zvereva, Novotna, etc.?
