The NFL recently passed a new rule allowing teams to designate a third emergency quarterback without adding them to the active game day roster. The Detroit Lions' proposal was approved to provide the team with a safety net if a quarterback has an accident or is sidelined. The designated emergency quarterback cannot be a member of the practice squad and must be on the 53-man roster. The purpose of the rule is to prevent teams from benching quarterbacks for poor performance. With teams now more motivated to keep a third quarterback, that shift could have an impact on roster decisions
