From the dawn of American football through the 1880s most offensive schemes focused on the running game. In a running based game plan the halfback was typically the cornerstone of the offense. This system focused on a physical run attack concentrated in the inside of the field, and therefore depended on a skilled "power back."
A 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. [1] There are usually one or two running backs on the field for a given play, depending on the offensive formation.
In football, the formation describes how the players in a team are positioned on the field. Many variations are possible on both sides of the ball, depending on the strategy being employed. On offense, the formation must include at least seven players on the line of scrimmage , including a center to start the play by snapping the ball.
In American football, the specific role that a player takes on the field is referred to as their "position". Under the modern rules of American football, both teams are allowed 11 players [1] on the field at one time and have "unlimited free substitutions", meaning that they may change any number of players during any "dead ball" situation.
The offensive backfield is an ambiguous generic term of football, which includes: (1) a place, namely the area of an American football field behind the line of scrimmage; and (2) a group classification of certain players positioned there, i.e., members of offense who begin plays behind the line, typically including any backs on the field, such as the quarterback, halfbacks and fullback.

The halfback then lines up behind either the left or right tackle. Once the run has been established, it can be a dangerous formation. Because of the real threat of a team running out of the pro-set, defenses must respect the play fake and play run [clarification needed]. This pulls the safety to the line and opens up the middle of the field deep.

The shotgun formation is a formation used by the offensive team in gridiron football mainly for passing plays, although some teams use it as their base formation. Instead of the quarterback receiving the snap from center at the line of scrimmage , in the shotgun he stands further back, often five to seven yards off the line.
