There is something to be said for continuity and allowing for growing pains over the course of development, which is the model adapted by the Pittsburgh Steelers since Dan Rooney assumed greater control of the team, basically over the course of the past fifty-plus years.
But there is also a lot of value in owning up to mistakes and avoiding the sunken cost fallacy, the idea that you can’t let things go because you made an investment in them, even though it would be more opportune to move on.
That seems like a pretty good description of the Cleveland Browns and their rapid-fire trek from Hue Jackson, who was fired in mid-2018, to Gregg Williams as interim head coach, to Freddie Kitchens in 2019, and finally to Kevin Stefanski this past season.
