Sean McVay Credits Shanahan Coaching Tree as Foundation of Modern NFL Offense

The Los Angeles Rams have long been recognized for their innovative offensive structure under head coach Sean McVay, a system that has helped shape success across multiple seasons and influenced coaching philosophies around the league. The approach has become one of the most widely studied frameworks in modern football.

While McVay’s name is often associated with the spread of this offensive style, he recently emphasized that its origins predate his tenure and trace back to a deeper coaching lineage that has shaped several branches of the NFL coaching tree.

That perspective came during an interview with media personality Kay Adams, where McVay was asked whether the system should be credited as the “McVay tree” or something else entirely. His response was direct and reflective.

McVay’s comments reinforced a broader acknowledgment within coaching circles that many of today’s offensive strategies are interconnected through decades of mentorship, adaptation, and shared philosophy.

1. McVay Points to Shanahan Origins

McVay was clear in attributing the foundation of the system to the coaching lineage of Mike Shanahan, stating that the structure of the offense began under his leadership. He noted that the evolution of the scheme is rooted in Shanahan’s early work in the NFL. He also highlighted the role of Shanahan’s son, Kyle Shanahan, who carried forward and refined many of the concepts that are now widely used across the league. McVay described Kyle Shanahan as a key influence during his own coaching development. McVay acknowledged that his own time working under that system helped shape his understanding of offensive game planning, particularly in situational football and red zone execution. Rather than claiming ownership of the modern adaptations, McVay emphasized continuity and mentorship as the driving forces behind the system’s evolution.

2. Coaching Connections Across the League

The influence of the Shanahan system extends across multiple coaching staffs in the NFL, with several head coaches and coordinators having worked within or alongside its principles at different stages of their careers. McVay noted that many of these coaches have crossed paths throughout their careers, sharing ideas and refining concepts that continue to evolve from one generation to the next. This interconnected network has helped spread the offensive philosophy across the league. He specifically referenced his time learning under Kyle Shanahan, recalling early responsibilities that included assisting with red zone play design and communication timing. Those experiences, he said, played a significant role in his development. The system’s adaptability has allowed it to remain relevant, with different coaches implementing variations based on personnel and team identity.

3. Lasting Influence on the NFL Landscape

The Shanahan coaching lineage continues to have a strong presence in the NFL, with its concepts visible in offenses across multiple teams. Its emphasis on timing, motion, and run-pass balance remains a defining feature of many modern playbooks. McVay’s remarks reflect a broader respect within coaching circles for the system’s longevity and adaptability. Rather than fading, it has expanded through successive generations of coaches. The Los Angeles Rams remain one of the most prominent examples of how those principles can be adapted at the highest level, blending traditional structure with modern innovation under McVay’s leadership. As coaching staffs continue to evolve, the influence of the Shanahan system is expected to persist, shaping offensive strategy across the league for years to come.
