On this episode of The Passing Lab, host Josh Herring sits down with Bethel University offensive coordinator and quarterbacks coach Colin Duling to break down the mechanics behind a high-efficiency passing game. Part of the Coach and Coordinator Network, this episode breaks down how to construct a unique, defense-straining offensive system without overwhelming your quarterback.
Coach Duling shares his blueprint for a highly evolved, yet incredibly simple RPO philosophy, highlighted by the concrete rules of the “zero read.” The conversation explores the micro-mechanics of pairing pass-run concepts, teaching crossing packages, and training wide receivers to make split-second option route decisions. From leveraging unbalanced formations and ineligible blocking schemes to structuring high-efficiency tempo and adjusting sideline-to-box play-calling, this interview is an essential masterclass for coordinators looking to play fast, play clean, and keep defenses on their heels.
