Maybe from being sacked by PDM and middle of the pack in the Giro the italia to win the Tour short after. EPO does that to you.
Anyway, let's imagine that EPO use starts to take place in 1991, when our hero loses against the big cheats (the small cheats he had managed to beat thorughout his career on bread and water).
EPO does provide a 10% to 15% improvement right?
Lemond wins in 1990 ( Echevarri picking Delgado over Indurain as leader of the team

)
Lemond speed 38.621 km/h
Chiapucchi, a definite EPO doper according to all comes second only 2 min 16 sec to Greg.
Shall we say the little Italian was already experimenting with it? What about Delgado, only 5 minutes behind Lemond and more than half of that time because of his blunder at the prologue.
After all, Delgado improvement on TT was as spectacular and suspicious.
Could it be possible that Lemond managed to beat the EPO dopers in 1990? Maybe his rivals were only blood doping. Othewise our Greg would have made mincemeat of Chiapucci on steroids and cortisone alone. Think about it, we are denigrating Lemond.
And it doesns't take a great deal of imagination that "en route" cyclists were doing what the Olympic US track team did, whose coach used to be Greg's coach by the way (mentioning this for reference purposes).
FFS even Milan, a football team, sorry, soccer, were rumoured to do blood doping, not to mention that Beckenbauer a German player of the 70' has confessed to it. And in th case of the German we are talking about the 70's.Since when footballers have been more advanced that cyclists taking doping? (except probably now

)
I mean, the more substances we make Lemond rivals take, the greater his legacy.
I propose from now on that Lemond last tour was won against EPO dopers and the toll it took on him caused those misterious illnesses that were to be his dismissal in 1991 and later years.
