Blitz (gridiron football)

In American football or Canadian football, a blitz is when additional players are sent to "rush the quarterback"—that is, try to tackle the quarterback or disrupt his pass attempt. The term is borrowed from the Blitzkrieg, the German strategy of "Lightning War" employed during World War II. Like the Blitzkrieg, the blitz is a concentration of force at high speed to force a breakthrough and proceed without regard to the flanks.
