Considering all the times ahead of her are Eastern Bloc 1980's, I'd assume I'm correct with this stance.
I'll admit I hadn't heard of Rollins before today, but I see she is 21 so I assume is in the American College system or something. To my eyes she at least looks womanly in pics, which is a circumstantial evidence indicator (and test of your own sexuality, appropriate in a Gay thread..)
But this is the US we are talking about, so I assume there will always be some dirty athletes in it for the money. Here in the UK, there's barely any money and if you are caught doping you are basically ostracised from athletics (although the rest of the world/international sports courts have ruled the BOA's Olympic life ban for dopers is 'a step too far', while reducing drugs bans to 2 years, but at least things are looking up with biological passports and what appears to be cleaner athletics).
