Bills

Brady returns as both head coach and offensive coordinator, bringing full continuity to his West Coast system based on his empirical playcalling data. His scheme emphasizes route concepts, timing, and balanced personnel usage, reflected in last season's 61% motion rate and balanced 51% under center approach. The transition comes on defense with new coordinator Jim Leonhard, who lacks clear empirical data or strong coaching tree connections. With mentors ranging from Vance Joseph's aggressive style (35% blitz rate) to Mike Pettine's more conservative approach (24% blitz rate), the defensive scheme defaults to Sound Multiple with low confidence. The contrast between Brady's established offensive identity and Leonhard's uncertain defensive direction creates partial continuity overall.
