Don’t see how you argue anything else
- tied (for now) for most slams
- only player with 2 wins at all 4 slams
- only player with a win at all masters 1000 series (and he has 2 at each)
- most career weeks at number 1
- career head to head over roger and rafa
And I’d also throw in:
- best Rafa twice at RG / hardest thing to do in sports
- came back from match points down to Roger in a Wimbledon final
- played the majority of his career in front of crowds cheering for the other guy
I think he’s probably got 2-3 solid years to chase calendar slam (or even golden slam this year), Serena’s 23 open era record, and Court’s 24 all time record
No argument from me. He's the GOAT for all the reasons you laid out. He's by far my least favorite of the big 3, but he's the best.
