Offensive formation - T-formation

"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."

"Offensive tactics in set pieces. ...
Throw-ins[edit]
How throw-ins are best handled depends on where it is:
(1) In one's own half the aim of a throw-in may be to retain possession in order to build up the next attack. The throw may or may not go toward the opponents' goal; the most unmarked player may be a full-back who is behind the ball. Such a throw followed by a quickly taken 'switch' pass can be an effective tactic. Under pressure however, the ball is often thrown up the line, toward the opponents' goal line to gain as much ground as possible.
(2) If the thrower is unmarked, a simple tactic is to take a short throw to the feet or chest of a marked player who immediately returns the ball to the thrower.
(3) In the last third of the pitch a player with a long throw can put pressure onto the defenders by throwing the ball deep into the opponents' penalty area, resulting in somewhat similar tactics to a corner kick situation, but with the added advantage of avoiding the offside trap, as an attacking player cannot be offside from a throw in. ...
Goal kicks.
A goal kick is an important 'set piece' that will occur many times in a game and yet few teams practice it. If taken quickly the kick may be taken short to a full-back who has run into a wide position. Although this may gain little ground it retains the all-important possession of the ball. A longer kick to the midfield is more common and it is vital that the midfield unit are in a position to receive it.
Corners.
A corner kick (or "corner") is a real goal scoring opportunity and it is essential to know who is the best at taking a good corner from both the left and right side of the pitch. A good corner will be aimed high across the goal and may be 'bent' towards or away from the goal. At least one of the forwards should be on or close to the goal line when the kick is taken.
Another tactic on a corner is to let the best shooter stay in the back "trash" position and have the defence worried about those up front. The player taking the corner kick makes a small pass back to the trash shooter who has time and space to take a good shot." [Association football tactics and skills. Wikipedia]

"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]

"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."

4–4–2.
This formation was the most common in football in the 1990s and early 2000s, so well known that it has even inspired a magazine title, FourFourTwo. The midfielders are required to work hard to support both the defence and the attack: typically one of the central midfielders is expected to go upfield as often as possible to support the forward pair, while the other will play a "holding role", shielding the defence; the two wide midfield players must move up the flanks to the goal line in attacks and yet also protect the fullback wide defenders."

"In American football, a 4–3 defense is a defensive alignment consisting of four down linemen and three linebackers. It is probably the most commonly used defense in modern American football and especially in the National Football League. ...
In the original version of the 4–3, the tackles lined up over the offensive guards and the ends lined up on the outside shoulder of the offensive tackles, with the middle linebacker over the center and the other linebackers outside the ends. In the mid-1960s Hank Stram developed a popular variation, the "Kansas City Stack", which shifted the strong side defensive end over the tight end, stacked the strongside linebacker over the tackle, and shifted the weakside tackle over center. At about the same time the Cleveland Browns frequently used a weakside shift. The Dallas Cowboys coach Tom Landry developed a "flex" variation, in order to take advantage of the quickness of his Hall of Fame tackle, Bob Lilly. In Tom Landry's original 4–3 defenses (4-3 Inside and 4-3 Outside), both defensive tackle were flexed. In the "flex", on a pro set right, with defensive keys showing a run to the right, the right defensive tackle would be flush on the line and was supposed to penetrate. The right defensive end and left defensive tackle were flexed two feet off the line of scrimmage, the right defensive end now head on with the left offensive tackle (i.e. a 4-2-2-5 front instead of the more common 5-2-2-5 front). This gave the defense a "zig zag" look unlike any other of its day. More modern versions of the 4-3 include the Tampa 2 scheme and the 4-3 slide." [4–3 defense. Wikipedia]
