What are the key differences between a fullback, a halfback, and a running back in football?

Answer 1

In football, a fullback typically plays closer to the line of scrimmage and is used for blocking and short-yardage runs. A halfback, also known as a tailback, is more of a versatile runner and receiver, often lining up farther back in the formation. A running back is a general term that encompasses both fullbacks and halfbacks, referring to any player who carries the ball in the backfield.
