+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 (1980–2025 here; league coverage is complete from 1999) — rooms the corpus cannot value are not shown.
