If you had watched the documentary, you would know that there were "Tough Man brawlers welcome" events started by two martial arts guys in Pittsburgh in the late 70's. They discovered some guy from Michigan who had "Tough Man boxing only" events. The Michigan guy was somehow able to claim that he used the name first, so the Pittsburgh guys changed their name to Tough Guys. The Michigan version had no rules and little to no safeguards for the fighters. They actually charged the fighters $0.50 for water. At one on the Michigan run Tough Man events, held in western PA, some poor out of work ex Marine died from injuries sustained in the fight. There was so much outrage, but people couldn't separate the two promoters. The PA legislature got involved and passed a bill to outlaw the "Tough Guy" events. Yes, the dirtbag from Michigan was allowed to continue, but the more ethical promoters had to give it up. The documentary mentioned a few different run ins with the athletic commission, which apparently was motivated by trying to save boxing from being steamrolled by this open brawling sport.
