you aren't using logic. if mc was was bad at it then she would have none. we saw that with ppl like henin. great on all surfaces but played in an era with great hc and grass players. if she played in mc's day, she would be wrongly considered just a clay court specialist.Try thinking logically. If three of the major events were on grass, that meant ALL the players had to be good on grass if they were to have any chance of winning. It's not as if Court double-bagelled everyone she played.
