He hasn't lost it yet, but it's quite a devasting thing to read. And if true, Landis just went from hero to zero/great hope to biggest dope faster than the french can yet again claim Lance was doped.
The only thing I can think of is that maybe he was on something for his hip that might have caused the test to come back positive.
Be honest, please: haven´t you wondered that Landis won the ride to Alpe d´Huez one day after he collapsed? That was more than a miracle. And I´m quite sure than Lance was doped, and so was the "ever 2nd" Jan Ullrich. Many many cases of blood doping haven´t been discovered and probably never will. Now it´s the tour winner. The Tour de France and the entire bicycle sports has two alternatives: either they allow those forms of doping which are hard to discover or they step up the controls so much that nobody can fall through the net (= taking the privacy from the riders and their teams).
