Thank you to NFL Flag for providing the following information on Player Positions and Game Play
FLAG FOOTBALL POSITIONS- 5 on 5.
Football offense positions:
Quarterback: The quarterback receives the snap and passes the ball or hands it off (they aren’t allowed to run with the ball after the snap).
Center: The center snaps the ball to the quarterback and then can run for a pass as a receiver.
Wide receiver: Depending on the play, some 5 on 5 teams field three receivers, or a couple receivers and a running back. The receiver runs designated routes to catch a pass (usually right and left receivers).
Running back: The running back takes a hand off and runs with the ball or throws it. They’re also eligible to receive a pass.
Football defense positions:
Defensive back: The defensive back covers wide receivers, either man-to-man or zone.
Safety: The safety stands further back from the line of scrimmage and is responsible for stopping opponents who get loose.
Rusher: The rusher attempts to prevent the quarterback from passing the ball (must be at least seven feet off the line of scrimmage at the snap to rush the passer).
