It must be said that Jager probably has been let off the hook a bit too easily for the leaked Athlete Blood Passport result. He may be American, friendly, good-looking - all which seems to suggest he isn't the type to dope - but the reality is the ABP has revealed he probably was doping. The burden of evidence on the ABP is set too high to convict many athletes at this point, but realistically it is highly suspicious, and it is definite American-favouritism to presume he is innocent and it was all a mix-up. If he was Kenyan or Russian people would probably be more critical.
Having said all of that... Willis was not on either Fancy Bears list, has never had another athlete accuse him of doping, and has never had a positive doping test. So stop with this false equivalency between Willis and Kiprop - it just isn't there. Kiprop is a proven doper; Willis is absolutely not. So, in many peoples' minds, Kiprop's positive test makes it fair to believe that Nick Willis is the true 2008 Olympic Champion.
