Basically everything that has been said in support of Rupp not doping could have been said (and was said) about Armstrong.
2 things that gave Armstrong away, and might be said about Farrah and Rupp - How are they fairing against known dopers - answer, about the same. Second, look at who he associates with - Armstrong with Ferrari, and Rupp with Nike/Alberto.
You seriously equate Alberto with Ferrari? That doesn't pass the giggle test. Salazar has had one athlete 'caught' - Mary Decker - and the test that got her was subsequently discontinued because of its numerous false positives.
get in touch with reality.
