What if someone really didn’t cheat but didn’t have the money and/or confidence to challenge a ban at CAS?
If WADA found what they were already testing for, I don’t see how a confession benefits it.
WADA wants them to testify about coaches and doctors. Athletes come and go but as we have seen with Kersee, doped coaches are forever (it seems).
What about for other sports? When Cano Robinson and Fernando Tatis, and other players, were caught cheating, there was no speculation that MLB coaches were involved. Barry Bonds went directly to Balco when he was using steroids.
I seriously doubt a coach was involved in Houlihan’s cheating. What would be the benefit to Schumacher to do so? He probably has lifetime employment, children attending college, and a mortgage to pay. He wasn’t going to risk destroying his life so that maybe Houlihan might win a Bronze.
I am okay with this. A simple reason is that it does not clog up the system or cost money to prosecute/defend the charges. If you don't then you incentivize everyone to fight the charges and that is costly.
