In this video, I break down our defensive line alignments and gaps, specifically focusing on the A, B, C, and D gaps. I explain the different techniques we use, including head up, inside, and outside shades, and how we adapt these for our linebackers and DBs by simply adding a zero to the numbers. I emphasize the importance of clear communication using our consistent numbering system to avoid confusion during play. I encourage you to apply these techniques in practice to enhance our defensive strategies. Please make sure to familiarize yourself with these alignments and communicate effectively on the field.
