A halfback is a position in American football, typically responsible for both running and receiving the ball. They often line up behind the quarterback and are crucial in executing plays, whether it involves running the ball on a rushing play or catching passes during a passing play. Halfbacks are known for their agility, speed, and ability to read defenses. In addition to their offensive duties, halfbacks may also contribute to special teams, particularly in kick return situations. The role of a halfback can vary depending on the team's offensive strategy, and they often work closely with the quarterback and offensive line to create successful plays.
