Connolly is someone who is underrated these days. At her peak she was the most dominant ever, particularly as a teenager. People say Seles was the most dominant teenager ever, and while she was impressive, her dominance from 16-19 absolutely pales in comparision to Connolly, and Connolly faced a much tougher field too. Whereas Seles only faced a subpar mostly slumping Graf who lost 7 of 8 matches to Sabatini, a granny 36 year old Navratilova, and 14-15 year old pre pubescent Capriati, Connolly had to face peak Hart, peak Brough, peak Fry (a career slammer), rising Gibson, and slightly past her prime Du Pont. Hart at her all time peak in 51-54 was way better than the subpar Graf of 91-early 93, Brough those years was much better than granny Navratilova of the early 90s, Fry was much better than a pre prime Sanchez, and Gibson and Du Pont those years were atleast better than Sabatini and baby Capriati, so you can see her competition was MUCH tougher than early 90s Seles. And still won all 9 slams she played vs Seles who won 8 of 13 slams from 90-early 93 but never won a Wimbledon. Not to downplay Seles, just reflecting that Connolly as a teenager was that much better and more dominant, against much tougher competition, as everyone remembers how great and dominant Seles was as a teenager, probably 2nd most ever to only Connolly, so by showing how much better still Connolly was it would really put Connolly into even more visible perspective.
And unlike Seles whose total dominance never would have continued even without the stabbing there was no end in sight to Connolly's dominance which likely wouldnt hav ended until the early 60s atleast. Surely she wins 35 slams minimum and is the hands down GOAT today without her horse riding accident. As such I feel she probably should be atleast top 5 all time, maybe top 3, but most today dont rate her there, forgetting just how dominant she was.
