Spy (gridiron football)In American football, a spy is a defensive player assigned to cover the opposing team's quarterback man-to-man. This strategy is generally used against "dual-threat" quarterbacks who are capable of rushing when passing plays break down. The defensive player floats near the line of scrimmage, following the quarterback's movements.[1] Spies are also sometimes known as "keys".[2] Generally, spies are linebackers.[3] References
