Provided that you ignore the fact that the Pittsburgh Steelers haven’t won a postseason game since 2016, it is perfectly within the norm for the organization to provide their head coach with an extension that leaves him with four years remaining.
Ordinarily, that occurs two years out in the form of a two-year extension. In this case, he had an option year for 2022 that Pittsburgh torn up and turned into a three-year extension. At the end of the day, it basically works out the same.
And for the Steelers, according to John Clayton, it’s just business as usual.
