A quarterback is a key player in American football, responsible for directing the team's offense. They receive the snap from the center and make quick decisions to either pass the ball, hand it off to a running back, or run it themselves. The quarterback's ability to read the defense and execute plays is crucial for the team's success. Quarterbacks are often seen as leaders on the field, communicating plays to teammates and maintaining composure under pressure. They typically have strong throwing skills and good athleticism, allowing them to evade defenders and make accurate passes to wide receivers or tight ends.
