A Running Back is a key player in American football, primarily responsible for carrying the ball during plays. They line up behind the quarterback and receive handoffs or passes, aiming to advance the ball down the field. Their speed, agility, and ability to evade defenders are crucial for gaining yards and scoring touchdowns. In addition to running, a Running Back also plays a vital role in blocking to protect the quarterback and create openings for other players. They often catch passes out of the backfield, making them versatile threats in both the running and passing game.
