It's very sad. My heart wants to believe he was clean but my head keeps coming back to the absence of an unequivocal statement that he did not dope rather than did not ever test positive. The USADA looks to be a bit of a kangaroo court and AFAIK has no power to strip him of his titles, but the stink will always linger unless he is proven innocent. You can't take away from him thr admiration he deserves for his fight back after the cancer but if he did dope then what about the damage done to the careers of any riders that he beat who were not doping?
PLus, of course, the damage to the reputation of the sport. Maybe it's down to the Brits now to revive it - please, please, please let all "our" lot be clean.
