Pressure defense
The pressure defense is the alignment when the defenders, mostly backs, attack the scrimmage line. In this case, more performers rush the line to make the quarterback execute an incompletion. The cornerbacks will line against the wide receivers despite their location closer to the scrimmage.
Of course, it aims to sack the QB before it passes the ball. That event happens because the offense must hurry behind the circle closes out. If the quarterback throws the ball, the high priority is to stop the ball carrier. Blitzing and sudden changes aim to get more time to reach the quarterback by slowing the receivers and running backs.
Previous spot
In American football, “previous spot” refers to the specific position on the playing field where the ball was most recently snapped or initiated for play. The implementation of penalties is frequently contingent upon the spatial relationship between the location of the infringement and the “previous spot.”
As an illustration, in American football, when an offensive team incurs a holding penalty, the subsequent enforcement of the penalty may originate from the “previous spot,” denoting the location on the field where the ball was last snapped. Consequently, the team responsible for the infraction experiences a reduction in yardage. The enforcement of fines can exhibit variations contingent upon the exact characteristics of the offense and additional contextual considerations. However, a commonly employed point of reference in many penalty assessments is the “previous spot.”
