The spread offense is an offensive scheme in gridiron football that typically places the quarterback in the shotgun formation, and "spreads" the defense horizontally using three-, four-, and even five-receiver sets. Used at every level of the game including professional (NFL, CFL), college (NCAA, NAIA, CIS), and high school programs across the US and Canada, spread offenses often employ a no-huddle approach. Some implementations of the spread also feature wide splits between the offensive linemen.
