Trevor Graham, the track coach who was banned from the sport for life for his role in the BALCO doping scandal, used the lead-up to the Olympics to offer scathing criticism of the worldwide anti-doping movement.

In a lengthy diatribe on Facebook, Graham contended the system in place does not care about clean athletes. He portrayed himself as the sport’s first true whistleblower and lit into pretty much every organization that has moved to punish him — saving the harshest words for the U.S. Anti-Doping Agency.

Among those Graham coached were Marion Jones and Tim Montgomery, each of whom was involved in high-profile doping cases. In 2003, Graham sent a syringe full of designer steroids to USADA, which began an investigation that helped uncover the BALCO scandal that implicated dozens of athletes for using the drugs. Graham was later given the lifetime ban for his role in the scandal.
