1. Chael Sonnen
Chael Sonnen is one of the most interesting people in the history of mixed martial arts, and he’s also been pretty honest about his history of PEDs. After a failed drug test at UFC 175 Sonnen admitted to everything, and took ownership of his failed tests which included 5 different banned substances. He retired from fighting afterwards, but was actually fired from his job as host of UFC tonight.
It looked to be the end of both his broadcasting and fighting career, but then four months later ESPN snatched him up.
