Wildcat formation describes a formation for the offense in gridiron football in which the ball is snapped not to the quarterback but directly to a player of another position lined up at the quarterback position (in most systems, this is a running back, but some playbooks have the wide receiver, fullback, or tight end taking the snap). The Wildcat features an unbalanced offensive line and looks to the defense like a sweep behind zone blocking. A player moves across the formation prior to the snap. However, once this player crosses the position of the running back who will receive the snap, the play develops unlike the sweep. Defending against the Wildcat is straightforward, but the defense does not always identify that a play will use the Wildcat, and preparing to defend against it may take practice time away from other preparation. If a defense interprets the Wildcat as a regular sweep play to one side, it may reduce its defense of the weak side and make it easier for the running back to advance the ball by running to that side. The Wildcat is a gambit rather than an overall offensive philosophy. It can be a part of many offenses. For example, a spread-option offense might use the Wildcat formation to keep the defense guessing, or a West Coast offense may use the power-I formation to threaten a powerful run attack. The Wildcat scheme is a derivation of Pop Warner's Single Wing offense which dates back to the 1920s. The Wildcat was invented by Billy Ford and Ryan Wilson, and was originally called the "Dual" formation. The offensive coaching staff of the Kansas State Wildcats, namely including Bill Snyder and Del Miller, made significant contributions to the formation's development throughout the 1990s and 2000s and is often cited as being the formation's namesake. It has been used since the late 1990s at every level of the game, including the CFL, NFL, NCAA, NAIA, and many high schools across North America. Specific coaching staffs have used it with various innovations and have given their versions a variety of names. ==History== One possible precursor to the wildcat formation was named the "wing-T",〔("'Wildcat' offense rooted in football's past" )〕 and is widely credited to being first implemented by Coach Tubby Raymond and Delaware Fightin' Blue Hens football team. Tubby Raymond later wrote a book on the innovative formation. The wildcat's similarity to the wing-T is the focus on series football, where the initial movements of every play look similar. For example, the wing-T makes use of motion across the formation as well in order to draw a reaction from the defense, but runs several different plays from the same look. Another possible precursor to the wildcat is the offense of Six-Man Football, a form of high school football, played mostly in rural West Texas and Montana, that was developed in 1934. In six-man, the person who receives the snap may not run the ball past the line of scrimmage. To bypass this limitation, teams often snap the ball to a receiver, who then tosses the ball to the potential passer. The passer may then throw the ball to a receiver or run with the ball himself. The virtue of having a running back take the snap in the wildcat formation is that the rushing play is 11-on-11, although different variations have the running back hand off or throw the football. In a standard football formation, when the quarterback stands watching, the offense operates 10-on-11 basis. The motion also presents the defense with an immediate threat to the outside that it must respect no matter what the offense decides to do with the football. 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「Wildcat formation」の詳細全文を読む スポンサード リンク
