Spiral (football)
In American football, a spiral is the continuous in-flight rotation around the longitudinal axis of a football following its release from the hand of a passer or foot of a punter. History Pop Warner is credited for teaching his players both the spiral punt and the spiral pass. Pass The development of the forward pass is traced to Eddie Cochems and Bradbury Robinson at St. Louis. Howard R. Reiter also claimed to develop the overhand forward pass. Punt Alex Moffat invented the spiral punt, described by one writer as "a dramatic change from the traditional end-over-end kicks." He also invented the drop kick.

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 States, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotation
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the rotation axis passes internally through the body's own center of mass, then the body is said to be ''autorotating'' or '' spinning'', and the surface intersection of the axis can be called a ''pole''. A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called ''revolving'' or ''orbiting'', typically when it is produced by gravity, and the ends of the rotation axis can be called the ''orbital poles''. Mathematics Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in space, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Football (gridiron Football)
In Canada and the United States, a football (also called a pigskin) is a ball, roughly in the form of a prolate spheroid, used in the context of playing gridiron football. Footballs are often made of cowhide leather, as such a material is required in professional and collegiate football. Footballs used in recreation, and in organized youth leagues, may be made of rubber, plastic or composite leather (high school football rule books still allow inexpensive all-rubber footballs, though they are less common than leather). History Early balls In the 1860s, manufactured inflatable balls were introduced through the innovations of English shoemaker Richard Lindon. These were much more regular in shape than the handmade balls of earlier times, making kicking and carrying easier. These early footballs were plum-shaped. Some teams used to have white footballs for purposes of night practice. The football changed in 1934, with a rule change that tapered the ball at the ends more and redu ...

Forward Pass
In several forms of football, a forward pass is the throwing of the ball in the direction in which the offensive team is trying to move, towards the defensive team's goal line. The forward pass is one of the main distinguishers between gridiron football (American football and Canadian football) in which the play is legal and widespread, and rugby football (union and league) from which the North American games evolved, in which the play is illegal. The development of the forward pass in American football shows how the game has evolved from its rugby roots into the distinctive game it is today. Illegal and experimental forward passes had been attempted as early as 1876, but the first legal forward pass in American football took place in 1906, after a change in rules. Another change in rules occurred on January 18, 1951, which established that no center, tackle, or guard could receive a forward pass, unless such a player announces his intent to the referee beforehand that he will ...

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] |
Eddie Cochems
Edward Bulwer Cochems (; February 4, 1877 – April 9, 1953) was an American football player and coach. He played football for the University of Wisconsin from 1898 to 1901 and was the head football coach at North Dakota Agricultural College—now known as North Dakota State University (1902–1903), Clemson University (1905), Saint Louis University (1906–1908), and the University of Maine (1914). During his three years at Saint Louis, he was the first football coach to build an offense around the forward pass, which became a legal play in the 1906 college football season. Using the forward pass, Cochems' 1906 team compiled an undefeated 11–0 record, led the nation in scoring, and outscored opponents by a combined score of 407 to 11. He is considered by some to be the "father of the forward pass" in American football. Early life Cochems was born in 1877 at Sturgeon Bay, the county seat of Door County on Wisconsin's Door Peninsula. He was one of 11 children, and "the s ...

Bradbury Robinson
Bradbury Norton Robinson Jr. (February 1, 1884 – March 7, 1949) was a pioneering American football player, physician, nutritionist, conservationist and local politician. He played college football at the University of Wisconsin in 1903 and at Saint Louis University from 1904 to 1907. In 1904, through personal connections to Wisconsin governor Robert M. La Follette, Sr. and his wife, Belle Case, Robinson learned of calls for reforms to the game of football from President Theodore Roosevelt, and began to develop tactics for passing. After moving to Saint Louis University, Robinson threw the first legal forward pass in the history of American football on September 5, 1906, at a game at Carroll College in Waukesha, Wisconsin. He became the sport's first triple threat man, excelling at running, passing, and kicking. He was also a member of St. Louis' "Olympic World's Champions" football team in 1904.Spalding's Official Athletic Almanac 1905Spalding's Official Foot Ball Guide ...

Howard R
Howard is an English-language given name originating from Old French Huard (or Houard) from a Germanic source similar to Old High German ''*Hugihard'' "heart-brave", or ''*Hoh-ward'', literally "high defender; chief guardian". It is also probably in some cases a confusion with the Old Norse cognate ''Haward'' (''Hávarðr''), which means "high guard" and as a surname also with the unrelated Hayward. In some rare cases it is from the Old English ''eowu hierde'' "ewe herd". In Anglo-Norman the French digram ''-ou-'' was often rendered as ''-ow-'' such as ''tour'' → ''tower'', ''flour'' (western variant form of ''fleur'') → ''flower'', etc. (with svarabakhti). A diminutive is "Howie" and its shortened form is "Ward" (most common in the 19th century). Between 1900 and 1960, Howard ranked in the U.S. Top 200; between 1960 and 1990, it ranked in the U.S. Top 400; between 1990 and 2004, it ranked in the U.S. Top 600. People with the given name Howard or its variants include: Given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alex Moffat (American Football)
Alexander Moffat (September 22, 1862 – February 23, 1914) was an American football player, coach and official. He played college football at Princeton University from 1882 to 1884 and was known as one of the greatest kickers in 19th century football. After his playing career ended, he remained active in the development of the game as a coach and founding member of football's rules committee. He was reported to have held a place in Princeton athletic history similar to that held by Walter Camp at Yale. Moffat was elected to the College Football Hall of Fame in 1971. Early years Moffat was born in Princeton, New Jersey, in 1862. He was the son of James C. Moffat, who was a professor at Princeton University for 40 years. Football player Moffat enrolled at Princeton and was a member of the Princeton Tigers football and baseball teams in the early 1880s. In baseball, he was Princeton's star pitcher for four years. In football, he played at the halfback position and developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drop Kick
A drop kick is a type of kick in various codes of football. It involves a player dropping the ball and then kicking it as it touches the ground. Drop kicks are used as a method of restarting play and scoring points in rugby union and rugby league. Also, association football goalkeepers often return the ball to play with drop kicks. The kick was once in wide use in both Australian rules football and gridiron football, but is rarely used anymore by either sport. Rugby Drop kick technique The drop kick technique in rugby codes is usually to hold the ball with one end pointing downwards in two hands above the kicking leg. The ball is dropped onto the ground in front of the kicking foot, which makes contact at the moment or fractionally after the ball touches the ground, called the ''half-volley''. The kicking foot usually makes contact with the ball slightly on the instep. In a rugby union kick-off, or drop out, the kicker usually aims to kick the ball high but not a great di ...
