I formation (Offense)

"The I formation is one of the most common offensive formations in American football. The I formation draws its name from the vertical (as viewed from the opposing endzone) alignment of quarterback, fullback, and running back, particularly when contrasted with the same players' alignments in the T formation.
The formation begins with the usual 5 offensive linemen (2 offensive tackles, 2 guards, and a center), the quarterback under center, and two backs in-line behind the quarterback. The base variant adds a tight end to one side of the line and two wide receivers, one at each end of the line." [I formation. Wikipedia]

"In American football, the pro set or split backs formation is a formation that was commonly used as a "base" set by professional and amateur teams. The "pro set" formation featured a backfield that deployed two running backs aligned side-by-side instead of one in front of the other as in traditional I-formation sets. It was an outgrowth of the original, three running back T-formation, with the third back (one of the halfbacks) in the T becoming a permanent flanker, now referred to as a wide receiver. ...
A common variant of this formation removes the tight end and replaces it with a third receiver in the "slot" position. The formation is utilized to remove a defensive player from the tackle box to give the offense a 7-on-6 matchup.
There are three formations in the pro set of forms: Pro, Ace, and Tree." [Pro set. Wikipedia]

"This base defense consists of four defensive linemen, three linebackers, and four defensive backs (two safeties, two corners). Against two-receiver offensive sets, this formation is effective against the run and the pass. In the original 4–3, defensive tackles would line up opposite the offensive guards, and defensive ends on the outside shoulders of the offensive tackles. On passing downs, the Mike (middle linebacker) is often responsible to cover any running backs, the Sam (strong-side linebacker) covers the Tight End, and the Will (weak-side linebacker) either covers a back or blitzes in an attempt to sack the quarterback. Though first used as a base defense by the New York Giants in 1956, plenty of teams experimented with it during the 1950s, and thus there are multiple claimed inventors of this defense. There are several different variations of the 4–3 defense such as the 4-3 under defense, 4-3 over defense, 4-3 umbrella defense, 4-3 swim defense, and 4-3 slide defense."

"In the sport of association football, each of the eleven players on a team is assigned to a particular position on the field of play. A team is made up of one goalkeeper and ten outfield players who fill various defensive, midfield and attacking positions depending on the formation deployed. These positions describe both the player's main role and their area of operation on the pitch." [Association football positions. Wikipedia]

"In American football, a T formation (frequently called the full house formation in modern usage) is a formation used by the offensive team in which three running backs line up in a row about five yards behind the quarterback, forming the shape of a "T".
Numerous variations of the T formation have been developed, including the Power-T, where two tight ends are used, the Pro T, which uses one tight end and one wide receiver, or the Wing T, where one of the running backs (or wingback) lines up one step behind and to the side of the tight end. Any of these can be run using the original spacing, which produced a front of about seven yards, or the Split-T spacing, where the linemen were farther apart and the total length of the line was from 10-16 yards."

"In association football, the formation describes how the players in a team are positioned on the pitch. Different formations can be used depending on whether a team wishes to play more attacking or defensive football. ...
The WM system was created in the mid-1920s by Herbert Chapman of Arsenal to counter a change in the offside law in 1925. The change had reduced the number of opposition players that attackers needed between themselves and the goal-line from three to two. This led to the introduction of a centre-back to stop the opposing centre-forward, and tried to balance defensive and offensive playing. The formation became so successful that by the late-1930s most English clubs had adopted the WM. Retrospectively, the WM has either been described as a 3–2–5 or as a 3–4–3, or more precisely a 3–2–2–3 reflecting the letters which symbolised it. The gap in the centre of the formation between the two wing halves and the two inside forwards allowed Arsenal to counter-attack effectively. The W-M was subsequently adapted by several English sides, but none could apply it in quite the same way Chapman had. This was mainly due to the comparative rarity of Alex James in the English game. He was one of the earliest playmakers in the history of the game, and the hub around which Chapman's Arsenal revolved." [Formation (association football). Wikipedia]

"In the sport of association football, each of the eleven players on a team is assigned to a particular position on the field of play. A team is made up of one goalkeeper and ten outfield players who fill various defensive, midfield and attacking positions depending on the formation deployed. These positions describe both the player's main role and their area of operation on the pitch. ...
Goalkeeper is the most defensive position in football. The goalkeeper's main job is to stop the other team from scoring by catching, palming or punching the ball from shots, headers and crosses. ...
Defenders play behind the midfielders and their primary responsibility is to provide support to the team and to prevent the opposition from scoring a goal. They usually remain in the half of the field that contains the goal they are defending. Taller defenders will move forward to the opposing team's penalty box when their team takes corner kicks or free kicks, where scoring with one's head is a possibility. ...
Midfielders (originally called half-backs) are players whose position of play is midway between the attacking forwards and the defenders. Their main duties are to maintain possession of the ball, taking the ball from defenders and feeding it to the strikers, as well as dispossessing opposing players. ...
Forwards (or strikers) are the players who are positioned nearest to the opposing team's goal. The primary responsibility of forwards is to score goals and to create scoring chances for other players." [Association football positions. Wikipedia]

"The shotgun formation is a formation used by the offensive team in American and Canadian football. This formation is used mainly for passing plays, although some teams use it as their base formation. In the shotgun, instead of the quarterback receiving the snap from center at the line of scrimmage, he stands farther behind the line of scrimmage, often five to seven yards back. Sometimes the quarterback will have a back on one or both sides before the snap, while other times he will be the lone player in the backfield with everyone spread out as receivers."

"The goal line is the chalked or painted line dividing the end zone from the field of play in American football and Canadian football. It is the line that must be crossed in order to score a touchdown
If any part of the ball reaches any part of the imaginary vertical plane transected by this line while in-bounds and in possession of a player whose team is striving toward that end of the field, this is considered a touchdown and scores six points for the team whose player has advanced the ball to, or recovered the ball in, this position. This is in contrast with other sports like Association football and ice hockey, which require the puck or ball to pass completely over the goal line to count as a score.
If any member of the offensive team is downed while in possession of the ball behind his own team's goal line, this is called a safety and scores two points for the defensive team.
If, during the course of play, a loose ball travels past the goal line and is recovered within the end zone, then it is a touchdown if recovered by the kicking team, or a touchback if recovered and downed by the receiving team.
In the event of a kick recovered in one's own end zone, the entirety of the ball must pass the goal line in order for the ball to be considered in the field of play, and not a touchback." [Goal line (gridiron football). Wikipedia]

The 2–3–5 was originally known as the "Pyramid", with the numerical formation being referenced retrospectively. ...
For the first time, a balance between attacking and defending was reached. When defending, the two defenders (fullbacks), would watch out for the opponent's wingers (the outside players in the attacking line), while the midfielders (halfbacks) would watch for the other three forwards.
The centre halfback had a key role in both helping to organise the team's attack and marking the opponent's centre forward, supposedly one of their most dangerous players.
It was this formation which gave rise to the convention of shirt numbers." [Formation (association football). Wikipedia]
