RZ is an abbreviation used in fantasy football that stands for "Red Zone". The red zone is the area on a football field between the 20-yard line and the goal line at either end of the field. When a players team is in the red zone, it means they are inside their opponents 20-yard line and have a quality opportunity to score points. The RZ designation can alert fantasy football owners to flip over to that specific game or use the RedZone channel to see if their player will find the end zone. Touchdowns are extremely important in fantasy football and are one of the main ways to accumulate fantasy points. If a player is in the red zone, they are more likely to score a touchdown than if they are on the other side of the field.
