She's still is a GOAT in my opinion, she outlived here contemporaries, Hingis, Clijsters, Davenport, Henin. Some name that I can think of right now.
Yes, as of now, she probably is. But I wrote "GOAT forever" and if she was as fit as the players I mentioned, I think no one would ever come close to what she would have achieved. Just like if Steffi Graf had a backhand
But these GOAT discussions are always a bit meh, because the game changes so fast. Put any of the Top10 WTA from 2020 in the Steffi Graf era and they would win every tournament basically imo. These players now have way better equipment, the game is faster, the players are insanely fit, spend hours in the gym, look after their diet etc. Then again put Steffi Graf in Margaret Court era and she herself would win everything there.
Steffi Graf owes many of her titles and victories in tennis to one tragic event, the attack of a sick person on Monica Seles at the 1993 Hamburg tournament.
By that point Monica Seles was much better than Steffi Graf and dominated women’s tennis like Serena Williams today.
If it weren't for that tragedy, no one would be talking about Stefa Graf today, but about Monica Seles.
It was a passing of the torch that time, from Monica Seles to Steffi Graf. And you are right, Monica is already dominating that time, its just unfortunate that this stabbing had happened, pushing her back and the true potential to stay at the top of the game.
I agree that we can't compare era's, it has been the case in many sports. Just like in tennis, when the sisters come into the scene, everything has change, Hingis was still the best women's player out there, until Serena took over.
