Doping

I think they pushed to the absolute limits of what is allowed within the rules, so using drugs that are banned in competition but not out of it, applying for TUEs when there was no real medical need, etc., but there's no evidence of crossing that line. By the rules of the sport, that means they are clean, irrespective of the ethics.

I'd argue that if you think what they were doing was in isolation, i.e. other teams weren't doing exactly the same, then you don't understand how professional sport works.

I'll give you a cow for them.

Yeah it looks sketchy as, but still not a smoking gun. Also I'd be wary of tarring other riders with the same brush
