National Football LeagueThe National Football League (NFL) is a professionalAmerican football league in the United States. Composed of 32 teams, it is divided equally between the American Football Conference (AFC) and the National Football Conference (NFC). The NFL is one of the major professional sports leagues in the United States and Canada and the highest professional level of American football in the world.
Defensive coordinatorA defensive coordinator (DC) is a coach responsible for a gridiron football team's defense. Generally, the defensive coordinator, offensive coordinator and special teams coordinator represent the second level of a team's coaching structure, with the head coach being the first level.
Offensive coordinatorAn offensive coordinator (OC) is a coach responsible for a gridiron football team's offense. Generally, the offensive coordinator, defensive coordinator and special teams coordinator represent the second level of coaching structure, with the head coach being the first level.
LinebackerLinebacker (LB) is a playing position in gridiron football. Linebackers are members of the defensive team, and typically line up three to five yards behind the line of scrimmage and so back up the defensive linemen. They play closer to the line of scrimmage than the defensive backs (secondary).
QuarterbackThe quarterback (QB) is a position in gridiron football who is a member of the offensive side of the ball and usually lines up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offense, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is almost always the offensive player that throws forward passes.
College footballCollege football (French: Football universitaire) is gridiron football that is played by teams of amateur student-athletes at universities and colleges. It was through collegiate competition that gridiron football first gained popularity in the United States. Like gridiron football generally, college football is most popular in the United States and Canada.
Defensive backIn gridiron football, defensive backs (DBs), also called the secondary, are the players on the defensive side of the ball who play farthest back from the line of scrimmage. They are distinguished from the other two sets of defensive players, the defensive linemen who play directly on the line of scrimmage, and the linebackers, who play in the middle of the defense, and between the defensive line and the defensive backs.
Running backA running back (RB) is a member of the offensive backfield in gridiron football. The primary roles of a running back are to receive handoffs from the quarterback to rush the ball, to line up as a receiver to catch the ball, and block. There are usually one or two running backs on the field for a given play, depending on the offensive formation.
Head coachA head coach, senior coach, or manager is a professional responsible for training and developing athletes within a sports team. This role often has a higher public profile and salary than other coaching positions. In some sports, such as association football and professional baseball, this role is referred to as the "manager," while in others, like Australian rules football, it is called "senior coach."
American footballTeam field sportAmerican football, referred to simply as football in the United States and Canada and also known as gridiron football, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end.
Lineman (gridiron football)In gridiron football, a lineman is a player who specializes in play at the line of scrimmage. The linemen of the team currently in possession of the ball are the offensive line (OL), while linemen on the opposing team are the defensive line (DL). A number of National Football League (NFL) rules specifically address restrictions and requirements for the offensive line, whose job is to help protect the quarterback from getting sacked for a loss or fumbling.*As an Amazon Associate I earn from qualifying purchases.
