True, there was little doubt about his own doping (no doping based on strong ethics) but the hesitation was about recollecting others doping. He definitely knew who, what & where. Also Lemond was definitely offered drugs as well. But he was a phenomenal cyclist. If you are wining easy (seen from his record from an early age) why would you dope. If you are already a superman, do you take drugs to become even more super? Think of the risks at that time, one of which was death. If he dabbled in doping, somebody would know as these things are not done independently. But he literally disappeared after 1990. If he was doping there would be 3 more tours for him 91,92,93 inspite of fatigue or other points that he gave as reasons for not doing well in those tours. At the height of you know who's career, he said that he would bring witnesses against Lemond for doping. So far there have been no such witnesses. Right after Coppi upto Contador, the top cyclists have been involved with drugs. There have been positives, witnesses, anecdotes, dodgy doctors etc. From what i know, the one exception is Lemond. While he himself probably didnot dope, the one little thing that i have against Lemond is that he has not grassed on anyone else who doped (probably cannot because of libel). He is more against dodgy doctors than poor cyclists.
