A discussion was had today on the Pat McAfee Show, focusing on the impact of a head coach calling either the defense or the offense. The emphasis was on the continuity a head coach serving as the offensive play-caller has with their quarterback, but based on the success various teams are having, there is a good argument for the opposite. The reigning Super Bowl champs, the Seattle Seahawks, have arguably the best defense in the league, which is called by their head coach Mike Macdonald. The Buffalo Bills, who have possibly the most efficient offense in the league and best quarterback in Josh Allen, is called by their head coach Joe Brady.

Which do you believe is more impactful to a team's success, head coach as offensive play-caller or defensive play-caller?
