Documented path
Born on Saint Croix, U.S. Virgin Islands, Duncan initially aspired to be an Olympic swimmer. After Hurricane Hugo destroyed the island's pool in 1989 and his mother died of cancer in 1990, he switched to basketball at age 14, taught by his brother-in-law. He played at St. Dunstan's Episcopal High School and then Wake Forest University (1993-97), where he became a consensus All-American and National College Player of the Year. Drafted #1 overall by the San Antonio Spurs in 1997, he won Rookie of the Year in 1998 and the NBA championship with Finals MVP in 1999.

Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Tim Duncan against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+2Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Started basketball at 14 but showed immediate natural talent — within a year was flashing potential at St. Dunstan's Episcopal. Drafted #1 overall in 1997 after a decorated Wake Forest career. Exceptional late-specialization talent, though not a childhood prodigy.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Working-class immigrant family from Anguilla on Saint Croix, U.S. Virgin Islands. Mother was a midwife, father a mason. No basketball background. Mother died of cancer when Duncan was 14. Modest circumstances with no domain connections.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Brother-in-law Ricky Lowery (former D-III player) taught him basketball at 14. Wake Forest coach Dave Odom discovered him through a U.S. junior team visit to St. Croix. Wake Forest provided elite college development. David Robinson and Gregg Popovich at the Spurs. However, late start and limited early access.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: High. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
Silence in a biography is not evidence that perseverance was absent.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Elite institution pipeline, Parent / family domain, Frontier geography.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Complementary team, Scarce skill depth, Elite ecosystem network.

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.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.

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.
