The hurry-up offense is an American football offensive style, which has two different but related forms in which the offensive team avoids delays between plays. The hurry-up, no-huddle offense (HUNH) refers to avoiding or shortening the huddle to limit or disrupt defensive strategies and flexibility. The two-minute drill is a clock-management strategy that may limit huddles but also emphasizes plays that stop the game clock. While the two-minute drill refers to parts of the game with little time remaining on the game clock, the no-huddle may be used in some form at any time. The no-huddle offense was pioneered by the Cincinnati Bengals and reached its most famous and complete usage by the Buffalo Bills, nicknamed the "K-Gun", during the 1990s under head coach Marv Levy and offensive coordinator Ted Marchibroda. No-huddle The no-huddle offense is usually employed as part of a hurry-up offense, but it is not necessarily an attempt to snap the ball (begin the play) more quickly. Rather, the lack of huddle allows the offense to threaten to snap the ball quickly, denying the defending team time to substitute players and communicate effectively between coaches and players. When operating in the no-huddle, the offense typically lines up in a predetermined formation at scrimmage, possibly with a predetermined play in mind. The quarterback may then call an audible, altering the play call based on a perceived weakness in the defense's response. Some teams use this methodology to react to the defense and will remain at this pre-snap state for a considerable time as the clock runs down, providing a stream of actual and counterfeit play changes. Development as a standard method The hurry-up offense is nearly as old as football itself. Huddles used to not exist. Michigan coach Fielding Yost was known as "Hurry up;" as he had Bennie Owen call signals for the next play even while still lying beneath the tackle pile from the previous snap. John Heisman's 1899 Auburn Tigers was noted for its speed. The first team to employ a version of the no-huddle approach as the normal offensive play strategy was the 1988 Cincinnati Bengals under Sam Wyche with Boomer Esiason as the quarterback. This approach, called the "attack offense", involved a number of strategies including shortened huddles and huddling much closer to the line of scrimmage than usual. The no-huddle approach was used by many teams before but in specific situations for
