I'm not sure I was qualified to evaluate what I was looking at (or that I would be today) and obviously that is not the full history of the sport. Like I know Hingis was hampered by injuries (Navratilova still widely rated as better, no?) and then going further back I really have little idea. Like how good was Athlea Gibson? Margaret Court is an extremely accomplished player but I couldn't come close to putting her in a modern context.
