Can a criminal ( as Bob Hewitt ) be a GOAT contender ?
Can a criminal be the GOAT ?
Can a player who says the public opinion of nonsense or atrocities against a group of persons being a GOAT contender ?
Or the GOAT ?
If Laver had been a serial killer or a drug dealer would be considered the same GOAT ?
If Bill Tilden was a pedophile would be considered the same GOAT ?
I suspect you are mixing up two very different ideas when you connected this post with a discussion on the Riggs/Court match. No one is suggesting playing exhibitions is a character flaw or that it disqualifies someone who plays in them from consideration, just that the results are rarely included as professional standard statistics. I will answer the abov in terms of homophobia allegations,
Its going to depend on whether you are defining personal character as part of what you are measuring. that is a personal call, just as other in intangibles off the court activity is, or how much weight you give doubles. If we are deciding that off the court behavior is part of what we are measuring, than philanthropic giving is going in the 'plus' column. Attributes like sportsmanship are also on the table, and we are now giving extra credit points to players who promote civil rights or other social change we laud while winning tournaments, like Arthur Ashe or Billie Jean King.
We also have to ask what to do with behavior that happens after the tennis playing career ends. Do they get points for becoming a nun and working with the poor like andrea jeager, and demerits for becoming a pastor and calling gay people sinners?
Personally, I prefer to leave the off-the court stuff off the court when measuring the play, and including it when measuring a total impact on the sport. When I am talking about GOAT player, I mean play, rather than the person. So yes bad people who's character while playing the sport would disqualify them from being in the Hall of Fame, could be GOAT from my normal point of reference. its already complicated enough to determine if Graf is GOAT over Williams or Lenglen or Court on that basis, without trying to include who was nicer, and more moral and who was nasty and selfish and refused to take in stray cats while training for Wimbledon.
That is certainly true if the conduct was in an 'afterlife' rather than during the time frame we are normally judging, namely from their first tournament on the main tour, to the last rather than from their first breath to their last.
Mostly this is all about being very specific in our definition of what is included or not before we start arguing. If
you are going to include matters of character, and matters outside the time frame of play as a matter of principal, then I would not call Court a GOAT tennis candidate when discussing the topic with you. I will also
not call Evert a GOAT candidate if you want to give doubles and mixed doubles equal weight. Evert then barely makes the top twenty list!
I'll adapt to your definition so that the conversation has meaning or I won't talk about it with you. I don't mind playing football on your field with your goalposts as long as I know the distance between them.
