The Pittsburgh Steelers posted a 6-4 record before firing offensive coordinator Matt Canada. They went 4-3 without him. That only tells a small fraction of the story, given that they had three different quarterbacks start at least two games during that time.
But Canada and his dismissal were without question a significant component of the story of the Steelers’ 2023 season. To start with, it marked the first time they’d ever fired a coach in-season. I’m not sure any other coach ever elicited a position for his firing, either.
Given the instability at quarterback over the final six games, it’s really hard to compare and contrast the offense with Canada as play-caller and the finale seven games with quarterbacks coach Mike Sullivan calling the plays and running backs coach Eddie Faulkner handling most of the rest of the load.
