Editing Cornerback (section)

===Cover 1===
The Cover 1 defense is an aggressive formation employed against offenses trying to gain short yardage. In the Cover 1 defense, one defender—normally a safety—plays deep zone downfield, providing security over the top and freeing the other safety to rush the line of scrimmage or drop back into coverage. Meanwhile, the corner's primary responsibility is to play on or off the receiver and not release him vertically. Defensive coordinators typically call for Cover 1 formations only when their cornerbacks are skilled at playing man-to-man coverage.
