The shotgun formation is a formation used by the offensive team in American and Canadian football. This formation is used mainly for passing plays, although some teams use it as their base formation. In the shotgun, instead of the quarterback receiving the snap from center at the line of scrimmage, he stands farther behind the line of scrimmage, often five to seven yards back. Sometimes the quarterback will have a back on one or both sides before the snap, while other times he will be the lone player in the backfield with everyone spread out as receivers. The shotgun formation can offer certain advantages. The offensive linemen have more room to maneuver behind the scrimmage line and form a tighter, more cohesive oval “pocket” in which the quarterback is protected from “blitzing” by the defense. If the quarterback has speed, mobility or both, he can use this formation to scramble before his pass; or, to run to an open field position in the defensive secondary or to the sideline, usually gaining first-down yardage. The formation also has weaknesses. The defense knows a pass is more than likely coming up (although some running plays can be run effectively from the shotgun) and there is a higher risk of a botched snap than in a simple center/quarterback exchange. If the defense is planning a pass rush, fast defensive players are given more open, and exposed targets in the offensive backfield; with less cluttered “blitzing” routes to the quarterback; and any other half-back in the offensive backfield in this formation. Combining elements of the short punt and spread formations ("spread" in that it had receivers spread widely instead of close to or behind the interior line players), it was said to be like a "shotgun" in spraying receivers around the field. (The alignment of the players also suggests the shape of an actual shotgun). Formations similar or identical to the shotgun used decades previously would be called names such as "spread double wing". Short punt formations (so called because the distance between the snapper and the ostensible punter is shorter than in long punt formation) do not usually have as much emphasis on wide receivers. ==History== The shotgun evolved from the single wing and the similar double-wing spread; famed triple threat man Sammy Baugh has claimed that the shotgun was effectively the same as the version of the double-wing he ran at Texas Christian University in the 1930s.〔David, Howard and Johnny Unitas (1981?).

The formation was named by the man who actually devised it, San Francisco 49ers coach Red Hickey, in 1960. John Brodie was the first NFL shotgun quarterback, beating out former starter Y. A. Tittle largely because he was mobile enough to effectively run the formation. The shotgun was briefly used by the New York Jets during the middle of the Joe Namath era, as documented in the 1971 Sporting News article "Joe and the Booyah Tribe", to give the bad-kneed, and often immobile quarterback more time to set up plays by placing him deeper in the backfield. But the formation was not again used on a regular basis until the 1975 season, and then only by the Dallas Cowboys, which used the shotgun frequently with Roger Staubach at quarterback. The Cowboy shotgun differed from the 49er shotgun as Staubach generally had a back next to him in the backfield (making runs possible), where Brodie was normally alone in the backfield. Since no other NFL teams used the formation during this time, some believed it had been invented by Tom Landry. Instead, Landry simply dusted off the old innovation to address a pressing problem: keeping Staubach protected while an unusually young and inexperienced squad (12 rookies made the 1975 Cowboys roster) jelled. The team ended up in the Super Bowl, in no small part due to its new use of the old formation. The shotgun became a "signature" formation for the Cowboys, especially during third down situations. The shotgun was adopted by more teams throughout the 1980s, and was part of almost every team's offense in the pass-happy 1990s. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shotgun formation」の詳細全文を読む スポンサード リンク
