Soccer (Football) Formation

"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 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]

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 American football, each team has eleven players on the field at one time. The specific role that a player takes on the field is called their position. Under the modern rules of American football, teams are allowed unlimited substitutions, that is teams may change any number of players after any play. This has resulted in the development of three "platoons" of players, the offense (the team with the ball, who is trying to score), the defense (the team trying to prevent the other team from scoring, and to take the ball from them), and the special teams (who play in kicking situations). Within those platoons, various specific positions exist depending on what the player's main job is." [American football positions. Wikipedia]
