You gotta love these guys logic:
someone who gets caught doping, lies about it until presented with proof, then admits that he did it once, alone, because he was mentally weak, noone knew about it or helped him etc, who then reinvents himself as 100% clean, reformed, hard working, saintly etc is 100% CREDIBLE and their word must not be challenged!
Someone who gets caught doping, lies about it for years, then changes tack and claims to be telling the whole story in presenting a fairly credible account of how him and others beat the system for years, has nothing to lose, drops accusations about how the best riders loaded up on dope, story taken seriously by FDA and USADA etc is ALWAYS a LIAR, and we mustn't believe ANY OF IT, as he just wants to RUIN CYCLING!
It's a daft position to take.
