6. Josh Barnett
Josh Barnett’s heavyweight reign was a tale of failed drug tests. It’s a shame because he is one of the most liked fighters on the roster. He had already failed a test before fighting Randy Couture and would fail another after beating the champion.
Crazily, he has just got a warning for his first drug test failure. USADA was a long way away. After the second, he got stripped of the title and he’d spend the next six years fighting in Japan. A long way away from any testing.
