The ‘Brockton Blockbuster’ held the heavyweight crown from 1952 up to 1956. And is still the only heavyweight champion to finish his career undefeated, holding the astonishing professional record consisting of 49 Wins (43 KO’s) included victories over Joe Louis, Jersey Joe Walcott and Ezzard Charles. Varying opinions on the real Rocky exist in boxing. Some say he was overrated and never fought the best despite facing the elite during that period others say he deserves the credit he gets as a true and great heavyweight champ. Although one thing is definite this man would have been a handful for any heavyweight champion in history due to his toughness and ferocity. Incredibly Rocky only had a 67” reach which is the same as Manny Pacquiao’s reach.
