After his Olympic gold medal win in the legendary Mexico Olympics in 1968, Foreman plowed over professional boxing opponents like blades of grass in the early ’70s. Here, he decimates undefeated heavyweight champion Joe Frazier in 1972, who had recently dispatched Muhammad Ali. He also mutilated the much-feared Ken Norton, who also had defeated Muhammad Ali, breaking his jaw the first time and nearly beating Ali in the rematch. When Foreman nearly broke Norton in half with his devastating punches, he became one of the most feared fighters of all time.
