Perhaps largely due to the fact that the Pittsburgh Steelers were successful offensively last season, I believe the fact of offensive coordinator Randy Fichtner’s maturation has been treated as something less significant than it actually is, or can be, for the team this year.
He may not be a spring chicken, and he has been in the NFL for over a decade, but Fichtner never called plays in a meaningful professional football game before the 2018 season. He was a rookie offensive coordinator and play-caller in that regard, and even in spite of their general success, it did show at times.
