This was indeed the Greatest!! Nobody thought Ali would make it 2 rounds with "The Bear' - Sonny Liston... Ali knocked him out twice but then because Ali refused induction into the Army to fight in Viet Nam (although he would have just been a moral booster and done exhibitions) he was striped of his title and missed three of his prime years (27 to 31). He came back however and became the only man to win back his title three times. This was long before all the ultimate fighting BS. The Champ then was indeed the Champ!!
