Keep in mind that after the charging letter came out, it was reported that Saugy said he would never testify that the TdS sample was positive. He was adamant that it was a borderline result, and that according to the standards of the time it could not be judged positive. This is consistent with Tygart’s saying Saugy said the sample “indicated” positive.
Also, while the “keys to the EPO test” quote is shocking, did Saugy actually say so in so many words, or did he just “nod his head”? A head movement is something someone could easily deny, or claim was misinterpreted. Saugy could also argue that all he did at the meeting was reassure LA that he would not have to worry about false positives, that he explained to him how the test distinguished natural from synthetic positives.
In any case, it’s unlikely that Saugy could have told LA anything that was not already in the public domain. There was some discussion of this on another thread here, and some were arguing that LA took information from this meeting to Ferrari, who used it to design a way to beat the test. I don’t buy that. By that time, 2002, the EPO test had already been published, and Ferrari would have been thoroughly familiar with it, knowing far more details about it than UCI could have communicated to a non-scientist like LA. Possibly Saugy could have been more specific about how the different isoforms are judged than was indicated in the published paper, but that information really wouldn't help someone beat the test. Ferrari's main insight was in realizing that an IV injection would be eliminated from the body fast enough to beat most tests, simply because there wouldn't be enough EPO present. I don't see how anything Saugy could have told LA/JB would have helped Ferrari come to this insight. Though this point was actually made in a paper published twenty years earlier, apparently no one at UCI or WADA was aware of it at that time, as they all later expressed surprise that Ferrari had come up with it.
So unless Saugy suddenly reverses his position, and confirms everything Tygart said or implied, I think much more than this statement would be needed to build a case against UCI. If there is still communication going on between LA and USADA (?), Tygart could have been sending a message to him: if you want your ban reduced, tell us exactly what happened at this meeting.
