We owe the man a huge debt of gratitude, as the foundation of the sport includes a good bit of his blood, sweat and tears, but it’s okay to call him on his nonsense when he invariably spews it. Yeah, I’m talking about the legendary Ken Shamrock, who lost to Royce Gracie at UFC 1 and then to Tito Ortiz over a decade later, yet refuses to fade away into ignominy. Shamrock was on AXS-TV’s “Inside MMA” last week, and when hosts Kenny Rice and Bas Rutten brought the conversation around to performance-enhancing drugs… well, see for yourself.
