Diagnosis in October 1996, last chemo in December 1996. All of 1997 training. Racing and training as a pro with the Tour in mind in Jan 1998. First Tour win in July 1999... slightly different timescale to the one you're suggesting and, as I said before, a case that has never and will never be repeated. The physiological and psychological changes in him could have been massive. I'm not saying he isn't guilty of doping and wouldn't be massively surprised if he was found so but I'd prefer to investigate all options and have solid evidence before passing judgement.
