The holder in a season is the player with the most accumulated era-adjusted value (VAL) across attributed franchise seasons through that year — whole seasons only, never a depth-chart claim. A claim needs 3+ attributed seasons; unsettled through 1970. Relocated eras carry forward with the franchise.

Stadium, market-population, title and handle data are curated public facts (Wikipedia/Census/official league facts). Fan Interest, Barometer and reach tier are transparently derived from those facts — weighted (market 0.4, venue 0.2, titles 0.25, heritage 0.15), min-max within MLB — derived structural proxy, not a survey. No fan survey, sentiment scrape, or follower count is used.
+2 more rooms with a shorter average hold.
Room tenures, not starting jobs — the corpus has no per-season depth chart, so holders can overlap (a successor often arrives before his predecessor leaves) and the measure is how often the room changed hands. A holder is a player who produced real value for this club during his years here, which is what separates holding the room from being on the roster. Detected from per-season VAL (1969–2026 here; league coverage is complete from 1999) — rooms the corpus cannot value are not shown.
+123 more one-club men with the franchise.
+689 more well-traveled players who wore the crest.
