Position designation is determined by the official depth chart published by the team for the specified week. If no official depth chart is available, the designation comes from official team communications (injury reports, press releases). For bye weeks, the market uses the last available depth chart before the bye. If the player is injured but still officially listed at the position, the market resolves to Yes. For postseason weeks, if the team is eliminated before that week, the market resolves to No. Practice squad and inactive players do not qualify unless officially promoted to the active roster at the specified position.
