I'd have to say Dan Hardy. My background is a little more varied than his. I had my black belts in judo and tkd by twelve as well as a blue belt in shotokan karate. I have competed at Golden Gloves level in boxing and have had more than my fair share of amateur kickboxing, muay thai, and wrestling matches. I've only competed in one bjj tournament and I got outpointed by a 2nd degree black belt under Renato Tavares. I was actually training for my pro debut in mma when I ripped my thigh muscle in half and spent the next three years walking with a damn cane.
With Hardy... I'm pretty much better at everything. More varied striking combined with takedowns and GNP. And he fights stupidly. Same plan everytime. Easy to plan for.
That is not dead which can eternal lie and withs strange aeons even death may die.
