The two-minute offense (sometimes known as the "two-minute drill") is a style of offensive gameplay in which the team with the ball aims to manage to clock while trying to score within the last two minutes of the first or second halves of the game. There tends to be virtually no running during this type of attack; passing is key, as an incomplete pass in American football stops the clock. Stepping out of bounds also stops the clock, and thus, the idea of any two-minute offense tends to be advancing the ball downfield in 5-15 yard pieces while throwing towards the sideline, so the receiver can step out of bounds before he is tackled.
The two-minute offense is usually only used when points are desperately needed in a short amount of time. This can mean either getting into the endzone or simply getting into the range of the attacking team's kicked, depending on how many points are needed. Especially in the latter case, using the sidelines is not the only way the offensive team can manage the clock. They can, of course, call timeouts if they have any remaining. The can also utilize a no-huddle ("hurry-up") offense, which can get the team ready for the next play quickly while keeping the defense on their heels. If all other options are exhausted, the quarterback as the option of "spiking" or "downing" the ball; a move wherein the quarterback receives the snap, then immediately throws the ball into the ground to stop the clock. The disadvantage to this is the loss of a down.
