Creed's tragic loss to Ivan Drago was an exhibition so that technically doesn't affect his W/L record. That being said, his only career loss was to the great Rocky Balboa and that bout went the full 15 rounds before Rocky won by a mere second in one of the greatest finishes in the history of the sport.
Ali was great, but let's not confuse him with the peerless Apollo Creed aka The Master of Disaster, The King of Sting, The Count of Monte Fisto!!!
