How far can Kyle Shanahan and Sean McVay go to evolve their own offenses? Each coach hires a defensive coordinator who is their perfect schematic opposite. In San Francisco, Shanahan and Robert Saleh's epic practice battles shape what are now the NFL's best defenses. In Los Angeles, McVay's and Brandon Staley's schemes clash as McVay becomes wholly obsessed with finding out how his offense can be solved. Host Jourdan Rodrigue studies the collision of apex systems and how the ripple effects start to shape each team - and the entire NFL.

Voices in the episode include McVay, Shanahan, Saleh, Staley, Thomas Brown, Andrew Whitworth, Mina Kimes, and Steve Wyche.
