Imitation is the highest form of flattery. But you don't have that O without that playcaller. It isn't just a "system" that you plug and play.
The way they run it just gives the playcaller some extra levers to pull. All of them call a play. They try to set a D up and call plays that exploit weaknesses. They all try to set up favorable match ups.
Heupel's O gives the playcaller the power to control situational substitutions, impact/deny defensive communication and audibles, and tire defensive players out both physically and mentally. It takes something special to do all the things every playcaller does plus use tempo like Heupel does to manipulate the opposition in critical ways.
