In the 1920s, Green Bay’s first head coaches favored a versatile backfield, rotating players like Johnny ‘Blood’ McNally to keep opponents guessing. Limited roster sizes and the rough, run‑heavy style of early football forced the team to value redundancy, sowing the seed for a systematic depth policy that would survive league expansions and rule changes. By the late 1930s, the organization formalized a practice of signing a third‑string runner each season, ensuring that injuries or fatigue would not cripple the offense.
The 1970s saw a strategic shift as the Packers embraced the emerging West Coast offense, which prized multiple rushing options to complement short passes. Coaches like Dan Devine recruited versatile backs such as MacArthur Lane, whose ability to catch out of the backfield added another dimension. This period cemented the belief that depth at running back could directly influence the success of a passing‑centric scheme.
