Right, time to move on from the lab debate, because clearly you believe there was some valid basis for the work done by Vrijmen. My contention is simple the basis of the report was flawed and he certainly did not act like an independant investigator (he never investigated the UCI involvement - Verbruggen actually handed over the signed test cards to l'Equipe if you remember).
There have been a few from the scientific community that have theorised that it is possible that cortisone metabolises somehow to testosterone and that is what caused the positive test. The argument against the value of the "exogenous" test largely rests with the belief that the test is unreliable. It does still seem to have the majority support in the medical community, as does the contention that testosterone levels were affected by other factors. But as you say, this is all irrelevant until it is proven in some sort of hearing or arbitration which will only happen next year.
There is a lot of noise about the principle of "innocent until proven guilty", but the reason those that test positive are treated as pariahs is simply because in 99.9% of cases they are found guilty. Personally, I believe the riders have created a community that is not trusted by the general public and so they are rightly viewed with skepticism. Until there is some level of transparency they will always be treated as guilty unless they can demonstrate their innocence. Perhaps if Floyd is innocent, his treatment would be different if he had been open and honest about his knowledge of teammates that were using a variety of drugs. It is worrying that the three current holders of the Grand Tours (Basso,Landis/Periero,inokourov) are all conspicious in their failure to take a stand on the drugs issue. That breeds suspicion in the mind of the public.
On the value of testosterone, it is widely believed in the peloton that there is benefit for short term recovery. Whether this is scientifically valid has no real impact on the riders who often revert to old wives tales and tradition, rather than science. Personally, I don't think Floyd ingested or took a patch. I believe he was on a comprehensive doping program and in the madness that happened following his spectacular blow-out on La Tousuirre, he missed a step in the program and got caught out. It would seem that the same happened with Hamilton and Heras. Armstrong, I believe was too meticulous. If he had an inkling that his urine samples would be tested for EPO 6 years after the 1999 race, I bet he would have taken adequate precautions.
It is interesting the view you have on l'Equipe - it is pretty common. I agree they have a torch to burn with Armstrong, but I don't believe that makes them lesser journalists - it just means they had more material to work with when it came to LA. Perhaps you should discuss l'Equipe with a few French speaking readers to understand what the newspaper is about and how good a publication it is.
