The document discusses the Severe Angle Blocking (SAB) blocking scheme. SAB is an aggressive angle blocking scheme designed to collapse the defense by having blockers attack at a 30-degree angle in unison. It gives blockers leverage and picks up blists and stunts. The key elements of SAB are exploding off the line of scrimmage, maintaining proper footwork and hat/shoulder placement, and driving defenders down an imaginary track while blocking with arms, hands and shoulders. Various blocking rules, adjustments, and examples of SAB schemes like Power, Counter, and Trap are provided.
