This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Mike Bossy's outcome attributable to any origin.
Luck is not a leftover score.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.
Within Athletes, Mike Bossy's starting-advantage total is at the 79th percentile. Separately, their built or converted leverage total is at the 58th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Bossy grew up in a hockey-obsessed working-class Montreal family with a backyard rink built by his father. He started skating at three, dominated youth hockey, and scored 309 goals in five QMJHL seasons before his NHL rookie year. At age 20-21, he set the NHL rookie goal record (53) and won the Calder Trophy, launching a career that included four straight Stanley Cups by age 26. His early advantage came from deep domain immersion in Montreal's hockey culture and extensive early reps rather than financial resources.
