Putting aside Paula's stated position on dopers, because she could be hiding something, one of the most telling thing is how her peers see her. Did any other female athletes accuse Paula of doping? I've seen a lot of quotes about the Chinese women, about the Turkish women, about the Russian women, but never did I read another female competitor accuse Paula of taking EPO to get her marathon performance.
Great reasoning, Einstein.
Radcliffe is the only obvious doper due to being the only one who does it so blatantly and in everyone's face.
