Measures how many NBA seasons a player competed in. Longevity is its own achievement — maintaining an NBA-level body and skillset across 15+ seasons requires exceptional dedication, adaptation, and durability. The Legacy Score (LS) caps the longevity bonus at 15 seasons, while PLR caps at 20. This factor captures the raw number. Players who played 20+ seasons are historically rare and score at the top.
