ZONE BLITZ

What is ZONE BLITZ?

ZONE BLITZ meaning “blitz” in which a defensive lineman drops back into zone pass defense instead of rushing; in contrast to normal blitz which requires the defense to be in a man pass defense because there are not enough defenders who are not rushing to cover all the necessary zones; in a sense, a zone blitz is not a blitz because instead of increasing the number of rushers as is normal with a blitz, only the position of the rushers is changed, namely, one of the defensive linemen does not rush; he drops into a zone instead and a linebacker or defensive back rushes in his place, albeit from a different starting point; requires an extraordinary lineman who can also play pass defense
