Muhammad Ali
Early career

Clay made his professional debut on October 29, 1960, winning a six-round decision over Tunney Hunsaker. From then until the end of 1963, Clay amassed a record of 19–0 with 15 wins by knockout. He defeated boxers including Tony Esperti, Jim Robinson, Donnie Fleeman, Alonzo Johnson, George Logan, Willi Besmanoff, LaMar Clark, Doug Jones, and Henry Cooper. Clay also beat his former trainer and veteran boxer Archie Moore in a 1962 match.

These early fights were not without trials. Clay was knocked down by both Sonny Banks and Cooper. In the Cooper fight, Clay was floored by a left hook at the end of round four and was saved by the bell, going on to win in the predicted fifth round due to Cooper's severely cut eye. The fight with Doug Jones on March 13, 1963, was Clay's toughest fight during this stretch. The number two and three heavyweight contenders respectively, Clay and Jones fought on Jones' home turf at New York's Madison Square Garden. Jones staggered Clay in the first round, and the unanimous decision for Clay was greeted by boos and a rain of debris thrown into the ring. Watching on closed-circuit TV, heavyweight champ Sonny Liston quipped that if he fought Clay he (Liston) might get locked up for murder. The fight was later named "Fight of the Year" by The Ring magazine.

In each of these fights, Clay vocally belittled his opponents and vaunted his abilities. He called Jones "an ugly little man" and Cooper a "bum". He said he was embarrassed to get in the ring with Alex Miteff and claimed that Madison Square Garden was "too small for me". Ali's trash talk was inspired by professional wrestler "Gorgeous George" Wagner 's, after he saw George's talking ability attract huge crowds to events. In a 1969 interview he stated that he met with George in Las Vegas in 1961, that George told him that talking a big game would earn paying fans who either wanted to see him win or wanted to see him lose, thus Clay transformed himself into a self-described "big-mouth and a bragger".

In 1960, Clay left Moore's camp, partially due to Clay's refusal to do chores such as washing dishes and sweeping. To replace Moore, Clay hired Angelo Dundee to be his trainer. Clay had met Dundee in February 1957 during Clay's amateur career. Around this time, Clay sought longtime idol Sugar Ray Robinson to be his manager, but was rebuffed.
