Kevin Garnett and Tim Duncan are the same age, but their career salary earnings are considerably different due to their decisions on when to enter the NBA.
Garnett entered the NBA directly from high school at the age of 19 and became the fifth overall pick in the 1995 NBA Draft.
Duncan, graduating from high school at 17, went to Wake Forest for four years and was the first overall pick in the 1997 NBA Draft.
Garnett has $315 million in career earnings compared to $224 million for Duncan, a difference of $91 million.
Garnett had a two-year head start and was earning $14 million when Duncan was making $3.4 million in his second season. Garnett signed a six-year, $126 million contract during the 97-98 season, which ultimately triggered a response from the owners in the 1999 lockout and impacted the earning potential of Duncan.
