Defensive Formation – 4-3 Defense Diagram

"Man-to-man defense is a type of defensive tactic used in team sports such as American football, association football, basketball, and netball, in which each player is assigned to defend and follow the movements of a single player on offense. Often, a player guards his counterpart (e.g. center guarding center), but a player may be assigned to guard a different position. The strategy is not rigid however, and a player might switch assignment if needed, or leave his own assignment for a moment to double team an offensive player. The term is commonly used even in women's basketball, though the gender-neutral 'player-to-player' also has some usage. ...
When defending the ball (i.e. guarding the man with the basketball) away from the basket in basketball, players typically should use a version of the following technique: The defender stands and faces the opponent. He is positioned between the ball and the basket and may be angled in one direction or another depending on the defensive scheme of that defender's team. He has his feet positioned beyond shoulder width with most of the weight distributed to the balls of his feet. However, the defender's heels should not be off the floor as this will put him off balance. The defender's knees should be bent at roughly a ninety degree angle with the bottom of his thighs parallel to the ground. This will place the defenders buttocks in a seated position. The defenders back should be straight with just a slight tilt forward. This will place the defender's head over the center of his body and maintain proper balance. Depending on the teachings of his coach, the defender should position his hands wide as if he were stretching his wingspan or place one hand high and one hand low." [Man-to-man defense. 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 American football, the dime defense is a defensive alignment that uses six defensive backs. It is usually employed in obvious passing situations.
The formation usually consists of six defensive backs, usually two safeties and four cornerbacks, and has either four down linemen and one linebacker, or three down linemen and two linebackers. This formation is to prevent the offense from completing a medium to long range pass play. This may be because the offense's running game is inefficient, time is an issue, or they need a long pass for a first down. It is also used against teams whose pass to run ratio predominately favors pass . The formation, however, is vulnerable to running plays as the formation is missing two linebackers, or a linebacker and a down lineman. A dime defense differs from the nickel in that it adds a sixth defensive back to the secondary. This sixth defensive back is called a "dimeback" (D). The defense gets its name because a dime is the next step up in US coin currency from a nickel. There are also 'quarter" and "half-dollar" formations (each protecting against progressively deeper thrown and more likely pass attempts)." [Dime defense. Wikipedia]
