Position eligibility is determined by a player’s past participation and info our data provider collects from NFL teams. Our data provider makes the final decision (there’s no set criteria) on position eligibility including when a new position is added. If it’s determined that a player’s primary position has changed, then that player gains eligibility for the new position but won’t lose their original designation.
