Background: Leonard, the fifth of seven children of Cicero and Getha Leonard, was born in Wilmington, North Carolina. He was named after Ray Charles, his mother's favorite singer. The family moved to Washington, D.C., when he was three, and they settled permanently in Palmer Park, Maryland when he was ten. His father worked as a supermarket night manager and his mother was a nurse.
Context: When Leonard decided to turn professional, Janks Morton introduced him to Mike Trainer, a friend of his who was an attorney. Trainer talked 24 of his friends and clients into underwriting Leonard's career with an investment of $21,000 to be repaid within four years at 8% interest. Trainer then made Leonard the sole stockholder in Sugar Ray Leonard, Inc. Angelo Dundee, Muhammad Ali's trainer, was brought in to be Leonard's trainer and manager. Many of the people being considered wanted absolute control and a cut somewhere near the manager's traditional 33%. Dundee had a different proposition. Although he would prescribe the training procedures, he would leave the day-to-day work to Dave Jacobs and Janks Morton. He would also choose Leonard's opponents. For his services, Dundee would get 15% of Leonard's purse.  Leonard made his professional debut on February 5, 1977 before a crowd of 10,270 at the Civic Center in Baltimore. He was paid $40,044 for the fight. His opponent was Luis "The Bull" Vega, whom he defeated by a six-round unanimous decision. After the fight, Leonard paid back his $21,000 loan to the investors.  In his fourteenth professional fight, Leonard fought his first world-ranked opponent, Floyd Mayweather, who was ranked seventeenth. The fight took place on September 9, 1978. Leonard won by a tenth-round knockout. A month later, Leonard defeated his old amateur nemesis Randy Shields by a ten-round unanimous decision.  On August 12, 1979, Leonard knocked out Pete Ranzany in four rounds to win the NABF Welterweight Championship. The following month, he made his first title defense against Andy Price. Many felt that Price would give Leonard a tough fight, but Leonard took him out in the first round, advancing his record to 25-0 with 16 knockouts.
