I guess it depends on weakness definition?! It has probably got some of the best players right now in the game (Djoko , maybe the GOAT; Svitolina; Tsitsipas); an all time Wimbledon great (Edberg) , Haas and Dell'Aqua (who both came through as wild cards). Cant find anyone to your taste?!
But it is all about favourites , in this poll, so no worries - i agree that some of the personalities in this group lag behind the others in terms of appeal!
