That's a ridiculous claim because it can't be falsified as long as you are not arguing with an unbeaten olympic champion. As long as an athlete has been beaten by somebody, you can always pull the "yeah well you know why you didn't win? Because you're clean, but everybody above you doped." Just like arguing "well we only lost the election cause the other side cheated."
