The BJJ black belt and the former UFC heavyweight champion who is known as Frank Mir has often been regarded as one of the strongest and most incredible Jiu Jitsu fighters in the history of UFC. Mir has always been a big guy. He weighs close to 260 pounds, but he always uses small man techniques to enjoy a more technical style. He does not focus on muscling out his fights, which means that he is much more technical in his approach. He believes that his technical knowledge is what gives him the advantage in most fights.
