1967 San Francisco 49ers NFL Play Charts and Defensive Strategies

This page from the 1967 First Official Illustrated Digest of the NFL details several strategic play diagrams utilized by the San Francisco 49ers, focusing specifically on offensive passing plays and defensive alignments. The top section features a schematic named "49er Turn-In Pass," illustrating player positions and routes, indicating players identified as H, S, and B, with the expected movement towards the center of the field. The second diagram, labeled "Square-Out and Down Pattern," emphasizes a combination route that enables flexible offensive tactics against defensive setups. The following sections depict two defensive formations: "Over-Shifted Odd Defense" and "Under-Shifted Odd Defense." Both diagrams demonstrate varying alignments of defensive players, aimed at countering offensive strategies with an emphasis on creating mismatches and disruption.
