So wait you're saying there has never been a real bare knuckle boxing champion, because I'm sure John L. Sullivan would disagree with you. Also what about the Muay Kaad Chauk tournament in Thailand. Bare Knuckle boxing in it's purest form allowed headbutts, elbows, even knees. There are still plenty of underground tournaments, but you're right that most aren't sanctioned. The difference between Kimbo and the guys that compete in these events is a boxing knowledge. Kimbo has no boxing knowledge.
