Good point, which makes me ask who the GOAT really is.
Serena -27 year career = 23 slams
Djokovic - 20 year career = 24 slams
STEFFI GRAF - 17 year career = 22 slams, plus the Golden slam (four slams and Olympic gold in a single year winning in all surfaces)
There should be an asterisk for Steffi Graff. She wouldn't have had that many slams if they hadn't stabbed Monica Seles.
