Full video on Glazier Drive: Building a Run Game & 2nd-Level RPOs out of the Spread Offense

OVERVIEW This video breaks down a modified "Man/ISO" scheme adapted for modern 11 personnel spread offenses. The system combines traditional ISO blocking principles with RPO (Run-Pass Option) concepts to create a versatile attack that works against multiple defensive fronts.

CORE CONCEPT The offensive line is assigned to block "down guys plus certain backers" - typically 5 total assignments to match the 5 offensive linemen. The quarterback reads the remaining unassigned second-level defenders to determine whether to hand off or throw. The goal is to always attack the lighter box while having answers for defensive overhang.

ASSIGNMENT STRUCTURE Against even fronts (4-man): O-line blocks 4 down linemen plus 1 middle linebacker. QB reads the 2 outside linebackers.

Against odd fronts (3-man): O-line blocks 3 down linemen plus 2 middle linebackers. QB reads the outside pressure.

The system aims to get 5 blockers on 5 defenders, leaving the QB to handle what's left through the pass game.

READ PROGRESSION Pre-snap reads focus on immediate blitz threats. Post-snap, the QB turns his body toward his primary read direction and attacks that side if defenders come down. The coach emphasizes QB footwork - "look like a shortstop turning two" with quick, efficient ball handling.

ROUTE COMBINATIONS Primary concepts shown include slant-bubble, hitch routes, and stacked screens. Wide receiver splits are emphasized to stretch apex defenders and force them to declare their intentions early.

RUN GAME PHILOSOPHY Running backs are coached to "stay square" and find the hole, which can hit anywhere from backside C-gap to playside C-gap. The system relies on creating even numbers in the box rather than trying to win disadvantageous situations.

GAME SITUATIONS Multiple examples show the concept working in crucial moments, including a state semifinals game where it helped control the clock with a 4-point lead and 4 minutes remaining.
