This document provides defensive play calls and alignments for a 3-3 stack defense against various offensive formations, including twins, trips, and spread sets. It lists the key responsibilities and techniques for each defensive player, such as the tackles focusing on the C gaps, safeties playing deep thirds of the field, and linebackers taking on blockers or covering running backs and tight ends. The defensive coordinator can use this sheet as a quick reference for calling the appropriate defense against different offensive personnel groupings and alignments.
