NBA legend Magic Johnson built a business empire following his Hall of Fame career with the Los Angeles Lakers. A five-time NBA champion, Johnson was the centerpiece of the "Showtime" Lakers during their prolific run in the 1980s. Johnson earned nearly $40 million in salary during his NBA career, including a 25-year, $25 million contract with the Lakers in 1981 that ranked as the richest deal in sports history at the time.
