Last year it was 20+ riders, the year before an entire team. There have been raids of hotel rooms, labs discovered, etc etc etc ad naueseum.
YOu have EVERY SINGLE WINNER for the last 12 years either admitting use, suspected of use or failed drug tests.
It is not condemning everyone for the actions of a few - it is the entire damn sport and you know it!
So everyone competing in the tour is doping even though they are tested every day and Vino is the only one testing positive so far? Interesting version of reality you live in. So quit watching cycling. I doubt anyone will notice.
