End Reverse
A reverse (sometimes referred to as an end reverse or criss cross) is a relatively common trick play in American football that involves one or more abrupt changes in the lateral flow of a rushing play. History The invention of the reverse is credited to Amos Alonzo Stagg. The invention of the ''naked'' reverse, i. e. a reverse run to the weak side, is credited to Pop Warner. Variations A classic reverse typically begins as a bootleg, sweep or end-around, but before the ball-carrier crosses the line of scrimmage he hands the ball off to a teammate, usually a wide receiver, running in the reverse (opposite) direction. Because many of the defensive players will have gravitated in the direction of the original rusher, if the second ball-carrier can outrun the defenders to the other side of the field, he has a very good chance to make a big gain. A variation of this play is a ''double reverse'', in which the second ball-carrier takes the ball all or part way back across the field befo ...

Trick Play
A trick play, also known as a gadget play, gimmick play or trickeration, is a play in gridiron football that uses deception and unorthodox tactics to fool the opposing team. A trick play is often risky, offering the potential for a large gain or a touchdown if it is successful, but with the chance of a significant loss of yards or a turnover if not. Trick plays are rarely used not only because of the riskiness, but also to maintain the element of surprise for when they are used. Trick plays take advantage of defenses' expectations and conventional wisdom, the set of basic principles to which most offenses adhere. Most offenses follow a basic set of conventions in that once the ball is snapped to the quarterback, it seldom changes hands more than once: a hand-off or pitch to a running back, or a forward pass, and the players with the best skill sets for those particular plays are the ones that will execute them. For example, the quarterback is by far the best thrower on the field ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Football
American football (referred to simply as football in the United States and Canada), also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins. American football evolved in the United S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Football Plays
In American football, a play is a close-to-the-ground plan of action or strategy used to move the ball down the field. A play begins at either the snap from the center or at kickoff. Most commonly, plays occur at the snap during a down. These plays range from basic to very intricate. Football players keep a record of these plays in a playbook. Order of a play A play begins in one of two ways: *A play from scrimmage begins when the ball is delivered from the center to a back, usually the quarterback. *A free kick Once the play begins, it will continue until one of the following events happens: *The ball carrier is down, usually defined as when any body part besides the hands and feet touches the ground. *The ball carrier's forward progress is stopped to the point where a stalemate occurs and it is clear that the ball cannot be advanced any farther, nor is he easily going down as defined above. *The ball carrier steps ''out of bounds''. *A forward pass touches the ground before it ...

Amos Alonzo Stagg
Amos Alonzo Stagg (August 16, 1862 – March 17, 1965) was an American athlete and college coach in multiple sports, primarily American football. He served as the head football coach at the International YMCA Training School (now called Springfield College) (1890–1891), the University of Chicago (1892–1932), and the College of the Pacific (1933–1946), compiling a career college football record of . His undefeated Chicago Maroons teams of 1905 and 1913 were recognized as national champions. He was also the head basketball coach for one season at Chicago (1920–1921), and the Maroons' head baseball coach for nineteen seasons (1893–1905, 1907–1913). At Chicago, Stagg also instituted an annual prep basketball tournament and track meet. Both drew the top high school teams and athletes from around the United States. Stagg played football as an end at Yale University and was selected to the first All-America Team in 1889. He was inducted into the College Football ...

Glenn Scobey Warner
Glenn Scobey Warner (April 5, 1871 – September 7, 1954), most commonly known as Pop Warner, was an American college football coach at various institutions who is responsible for several key aspects of the modern game. Included among his innovations are the single and double wing formations (precursors of the modern spread and shotgun formations), the three point stance and the body blocking technique. Fellow pioneer coach Amos Alonzo Stagg called Warner "one of the excellent creators". He was inducted as a coach into the College Football Hall of Fame as part of its inaugural class in 1951. He also contributed to a junior football program which became known as Pop Warner Little Scholars, a popular youth American football organization. In the early 1900s, he created a premier football program at the Carlisle Indian Industrial School—a federally-funded, off-reservation Indian boarding school. He also coached teams to four national championships: Pittsburgh in 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bootleg Play
In American football, a bootleg play is a play in which the quarterback runs with the ball in the direction of either sideline behind the line of scrimmage. This can be accompanied by a play action, or fake hand off of the ball to a running back running the opposite direction. Overview The quarterback can be accompanied by an offensive lineman to block for him, or run without a blocker, which is known as a naked bootleg or waggle. More complex versions involve multiple offensive linemen moving with the quarterback to block and multiple false hand offs; one such variation is known as a rollout. After escaping the area behind the offensive line, the quarterback may either throw a pass downfield or run with the ball himself to gain yardage. A bootleg is called to confuse the defense, by moving the quarterback away from where they expect him to be, directly behind the center. The quarterback's motion may also attract the attention of the defensive backs, allowing one of the recei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweep (American Football)
A sweep is an outside running play in American football where a running back takes a pitch or handoff from the quarterback and starts running parallel to the line of scrimmage, allowing for the offensive linemen and fullback to get in front of him to block defenders before he turns upfield. The play is run farther outside than an off tackle play. Variants of the sweep involve the quarterback or a wide receiver running with the ball, rather than a running back. When a wide receiver runs with the ball, it is known as a jet sweep. Types of the sweep Toss sweep A toss sweep is a play that is usually run out of the I formation or single set back formation. In recent years, it has also been run out of the pistol formation. The quarterback takes the snap, reverses out, then tosses the ball to the tailback. When run from the I formation, it allows the fullback to pick up any defenders who have penetrated into the backfield. Blocking from the offensive line ranges from st ...

End-around
The end-around is a play in American football in which an end or wide receiver crosses the backfield towards the opposite end of the line and receives a handoff directly from the quarterback. The receiver then may proceed to do one of two things: he either runs the ball towards the line of scrimmage in order to gain yardage, or more rarely, attempts to pass to another eligible pass receiver. Both versions of the end-around are uncommon and can be considered trick plays. The play can also be combined with a Statue of Liberty play. The end-around should not be confused with an end reverse, in which the receiver takes a handoff from a player who has already taken a handoff from the quarterback. End-arounds are usually preferred to reverses in the NFL; although they are less convincing, they offer lower risk. End-arounds offer less chance of a fumble, as there is only one handoff rather than two. Also, end-arounds require less time to complete, thus reducing the chance of a large l ...

Line Of Scrimmage
In gridiron football, a line of scrimmage is an imaginary transverse line (across the width of the field) beyond which a team cannot cross until the next play has begun. Its location is based on the spot where the ball is placed after the end of the most recent play and following the assessment of any penalty yards. History The line of scrimmage first came into use in 1880. Developed by Walter Camp (who introduced many innovations that are part of the modern game of American football), it replaced a contested scrimmage that had descended from the game's rugby roots. This uncontested line of scrimmage would set into motion many more rules that led to the formation of the modern form of gridiron football (although the Canadian rules were developed independently of the American game, despite their similarities). Dimensions A line of scrimmage is parallel to the goal lines and touches one edge of the ball where it sits on the ground before the snap. In American football, th ...

Halfback Option Play
The halfback option play is an unorthodox play in American and Canadian football. It resembles a normal running play, but the running back has the option to throw a pass to another eligible receiver before crossing the line of scrimmage. The key to the play is fooling the defensive players, primarily the defensive backs. If the linebackers and/or the defensive line are fooled and believe the ball carrier is attempting a run, they will pursue the runner, abandoning their pass defense responsibilities and thereby leaving pass receivers uncovered. If the defensive backs are not fooled, the running back carrying the ball does have the option to run, instead of risking an incomplete pass or an interception. This play is not as popular as it once was as defensive players are expected to cover receivers until the football crosses the line of scrimmage on running plays. The running play that halfback options usually resemble is a sweep play. Sometimes the quarterback will run out of the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Football Strategy
Strategy forms a major part of American football. Both teams plan many aspects of their plays (offense) and response to plays (defense), such as what formations they take, who they put on the field, and the roles and instructions each player are given. Throughout a game, each team adapts to the other's apparent strengths and weaknesses, trying various approaches to outmaneuver or overpower their opponent in order to win the game. Offensive strategy The goal of the offense is, most generally, to score points. In order to accomplish this goal, coaches and players plan and execute plays – based on a variety of factors: The players involved, the opponent's defensive strategy, the amount of time remaining before halftime or the end of the game, and the number of points needed to win the game. Strategically, the offense can prolong their possession of the ball to prevent the opponent from scoring. Offensive scoring chances, or drives, end when they cannot move the ball 10 yards or t ...
