Ali, Frazier & Foreman are 3 of the greatest heavyweights of all time, and are also 3 of the biggest names in boxing history - achieving accomplishments beyond belief. Early in their careers when they were considered green, they all had tough, and somewhat controversial decision wins in their favour against journeymen (I'm not sure if Bonavena was a journeyman at the time or not). Who do you think had the most controversial win?
