Quite possibly the most tested athlete in the history of sport, and he never failed one. His blood was monitored for years by doctors who were looking for recurrance of cancer. His blood never changed. No drug trail. No money trail.
USADA, this hunt by you is a "guilty until proven innocent" endeavor. I don't care if they think he did it or not. If you can't prove he did it by the rules and testing that you had in place, - the rules you created - then shut up. What are you going to do with the 7 titles you strip from him? Are you going to give it to the 3 runner ups who all tested positive for doping? You can't come back years after the fact and say, "I know you passed all of our tests, but we still think you cheated. Others say you cheated too, so you must have cheated."
Armstrong stopped fighting when it was clear that no evidence he could provide would prove him innocent. Circumstantial evidence and testimony by others was considered suficient to proclaim him guilty, in spite of the scientific evidence to the contrary.
I, like everyone else, don't have a clue whether he did it or not. All I know is that he never failed a test. Not one. Not before races, during races, or after races. If he was cheating, he somehow was able to do what no one else was able to do, including Floyd Landis and some of his other American Teammates. How do you explain that?
