Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Tim Duncan's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Tim Duncan's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Born to Ione (a midwife) and William Duncan (a mason) on Saint Croix, U.S. Virgin Islands. Both parents were immigrants from Anguilla. His mother died of breast cancer in 1990 when Duncan was 14. His sister Tricia swam for the U.S. Virgin Islands at the 1988 Olympics.
No basketball background in family; sister was an Olympic swimmer and brother-in-law Ricky Lowery was a former Division III basketball player who taught Duncan the game. Family valued education, with mother's deathbed wish that Duncan graduate from college.
Duncan grew up in the U.S. Virgin Islands in a working-class immigrant family. He started basketball late at 14 after his mother's death and a hurricane destroyed swimming facilities. His brother-in-law, a former college player, provided initial coaching. Wake Forest University's coaching staff discovered him and developed him into a national college player of the year. The San Antonio Spurs drafted him #1 overall in 1997, and he won Rookie of the Year and then NBA championship with Finals MVP by age 23. His late start was offset by exceptional physical attributes and the elite NBA pipeline of the Spurs organization alongside David Robinson.
