Raf was right. Disposable cups.
I wouldn't go that far, and to be fair, one day the fantasy may very well turn into fact, they are very good at what they do. That's part of the problem, they are all very good at what they do, and while one or two may be at the top at any given moment none of them have as yet that really unique and iconically 'it' factor that sets them not only above but also apart from their countrywomen. Part of that may be their extreme youth, part of it may simply be they tend to blur in the public eye.
I just think of all the predicted-to-be-GOATS (and god, there have been a lot of them) who have for one reason or another faltered or fallen back. Let's just wait till one of those girls actually has pulled herself off the revolving wheel and maybe just maybe had at least one or two GOAT-worthy seasons before handing them the label, hmmm?
