Blitzing
In gridiron football, blitzing is a tactic used by the defense to disrupt pass attempts by the offense. During a blitz, a higher than usual number of defensive players will rush the opposing quarterback, in an attempt either to tackle them or force them to hurry their pass attempt. In practice, a blitz involves five or more players rushing during a single down, rather than the four or three rushers used during normal play. For example, in a defense that normally uses four defensive linemen to rush, a blitz can be created by adding one or more linebackers or defensive backs. Blitzing is a higher-risk strategy, as fewer defensive players are left to cover receivers or to defend against running plays. However, a successful blitz will result in a sack or will force the quarterback into making an error. The term "blitz" is German for "lightning" and a reference to the blitzkrieg tactic of World War II. History The term "red-dog" referred to a rushing linebacker that created ...

Zone Blitz
In American football, a zone blitz is a defensive tactic that sends additional players to Pass rush, rush the opposing team's quarterback, whilst also unexpectedly redirecting a supposed pass rushing player into American football strategy#Pass defence, pass coverage instead. This tactic also includes Zone defense in American football, zone coverage (rather than man-to-man coverage). Like a conventional Blitz (gridiron football), blitz, the zone blitz tactic assigns five or more players to rush the quarterback in a single Down (gridiron football), down, rather than the usual three or four players. However, unlike a conventional blitz, the zone blitz uses players who are initially positioned to rush (for example, the defensive ends) to instead give pass coverage. For example, a zone blitz may involve two linebackers adding to the rush of three Lineman (gridiron football)#Defensive line, defensive linemen, while a fourth lineman unexpectedly moves into pass coverage.

4–3 Defense
In American football, a 4–3 defense is a defensive alignment consisting of four down linemen and three linebackers. It is called a "base defense" because it is the default defensive alignment used on "base downs" (1st and 2nd downs). However, defenses will readily switch to other defensive alignments (such as a nickel defense or a dime defense) as circumstances change. Alternatively, some teams use a 3–4 defense. History Early in the history of the National Football League, teams stacked the defensive line of scrimmage with seven linemen, typically using a 7-diamond or the 7-box. With the liberalization of the forward passing rules in 1933, the defenses began to evolve along with the offensive changes, and by the later 1930s, the standard defense in the NFL and college was the 6–2. The successes of the T formation and the introduction of free substitution, abolishing the one-platoon system, in the 1940s led to the almost universal adoption by 1950 of the five-m ...

Pass Rush
On defense in gridiron football, a pass rush is charging across the line of scrimmage towards the quarterback in an effort to stop or " sack" them. The purpose is tackling, hurrying or flushing the quarterback out of his protective pocket or the play's design. "Pressures" and "hurries" are terms used to describe pass rushes which successfully alter a quarterback's performance on a play — forcing them to throw before they find their best target or scramble out of the pocket to elude being tackled — that fall short of completed sacks. A related form of defensive rush is to disrupt or sack a kicker attempting to kick a field goal, extra point, or punt the ball. On offense, "rushing" is to run forward with the ball to gain yardage. In both college and professional football, getting a strong pass rush is an important skill, as even an average quarterback can be productive if he has enough time to find an open receiver, even against a good secondary. To increase pressure, team ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running 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 American football plays#Offensive terminology, handoffs from the quarterback to Rush (American football)#Offense, rush the ball, to line up as a receiver to catch the ball, and Blocking (American football), block. There are usually one or two running backs on the field for a given play, depending on the offensive formation. A running back may be a Halfback (American football), halfback (in certain contexts also referred to as a "tailback" — see #Halfback/tailback, below), a wingback (American football), wingback, or a Fullback (American football), fullback. A running back will sometimes be called a "feature back" if he is the team's key player/more prominent running back. With the increase in pass-oriented offenses and single set back formations, it is more common to refer to these players as simply running backs. Halfback/tailbac ...

Linebackers
Linebacker (LB) is a playing position in gridiron football. Linebackers are members of the defensive team, and typically line up three to five yards behind the line of scrimmage and so back up the defensive linemen. They play closer to the line of scrimmage than the defensive backs (secondary). As such, linebackers play a hybrid role and are often the most versatile players on the defensive side of the ball; they can be asked to play roles similar to either a defensive lineman (such as stopping the runner on a running play) or a defensive back (such as dropping back into pass coverage). How linebackers play their positions depends on the defensive alignment, the philosophy of the coaching staff, and the particular play the offense may call. Linebackers are divided into middle linebackers, sometimes called inside linebackers, and outside linebackers. The middle linebacker is frequently the "quarterback of the defense". His central role on the field means he is in the best posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Safety (American Football Position)
Safety (S), historically known as a safetyman, is a position in gridiron football on the American football positions#Defense, defense. The safeties are defensive backs who line up ten to fifteen yards from the line of scrimmage. There are two variations of the position: the free safety (FS) and the strong safety (SS). Their duties depend on the defensive scheme. The defensive responsibilities of the safety and cornerback usually involve pass coverage towards the middle and sidelines of the field. While American (11-player) formations generally use two safeties, Canadian (12-player) formations generally have one safety and two Halfback (Canadian football), defensive halfbacks, a position not used in the American game. As professional and college football have become more focused on the passing game, safeties have become more involved in covering the Eligible receiver, eligible pass receivers.Safeties are the last line of defense; they are expected to be reliable tacklers, and many ...

Quarterback Sack
In gridiron football, a sack occurs when the quarterback (or another offensive player acting as a passer) is tackle (football move), tackled behind the line of scrimmage before throwing a forward pass, when the quarterback is tackled behind the line of scrimmage in the "passing pocket, pocket" and without clear intent, or when a passer runs out of bounds behind the line of scrimmage due to defensive pressure. This often occurs if the opposing team's defensive team, defensive line, linebackers or defensive backs are able to apply pass pressure (also called a pass rush) to quickly get past blocking (American football), blocking players of the offensive team (the quarterback's protection), or if the quarterback is unable to find an available eligible receiver (including wide receivers, running backs and tight ends) to catch the ball, allowing the defense a longer opportunity to tackle the quarterback. A sack is advantageous for the defending team as the offense loses a Down (gridiro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interception
In Ball game, ball-playing Competitive sport, competitive team sports, an interception or pick is a move by a player involving a pass of the ball—whether by foot or hand, depending on the rules of the sport—in which the ball is intended for a player of the same team but caught or otherwise brought under control by a player of the opposing team, who thereby usually gains possession of the ball for their team. It is commonly seen in football, including American football, American and Canadian football, as well as association football, rugby league, rugby union, Australian rules football and Gaelic football, as well as any sport by which a loose object is passed between players toward a goal. In basketball, this is called a Steal (basketball), steal. Gridiron football In American football and Canadian football, an interception occurs when a forward pass that has not yet touched the ground is caught by a player of the defensive team. This leads to an immediate change of possess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fumble
A fumble in gridiron football occurs when a player who has possession and control of the ball loses it before being downed (tackled), scoring, or going out of bounds. By rule, it is any act other than passing, kicking, punting, or successful handing that results in loss of ball possession by a player. Unlike other events which cause the ball to become loose, such as an incomplete pass, a fumbled ball is considered a live ball, and may be recovered and advanced by any member of either team. A fumble may be forced by a defensive player who either grabs or punches the ball or butts the ball with their helmet (a move called "tackling the ball"). A fumbled ball may be recovered and advanced by either team (except, in American football, after the two-minute warning in either half/overtime or on 4th down at any point during the game, when the fumbler is the only offensive player allowed to advance the ball, otherwise the ball is ruled dead at the spot of the fumble, except when it is ...

Checkdown
In gridiron football, a checkdown pass is when the quarterback attempts to complete a short, accurate pass, typically to a running back or tight end, as a last option when the primary option(s) as designed by the play call are covered. The term means that the quarterback has "checked down" his list of receivers. Because the quarterback does not look for the checkdown pass until after they have scanned for open receivers down the field for about 3–4 seconds, the defensive line has had time to enter the backfield and so a checkdown pass is often thrown in the face of pressure from the defensive line. Alternatively, if the quarterback is inexperienced or the defensive team has sent a blitz, with linebackers and/or defensive backs also looking to sack the quarterback, the checkdown may also turn out to be the quarterback's second or even first look. A screen pass A screen pass is a play in gridiron football consisting of a short pass to a receiver who is protected by a screen of ...
