Steelers HC Mike Tomlin indicated that they would make changes this year, but most have found those changes underwhelming. While many wanted a whole slew of coaches fired, very little of that took place. They moved on from two position coaches, though, and one of the new hires previously worked here two years ago.
The Steelers did make some meaningful changes in terms of personnel, most notably at wide receiver. They made a blockbuster trade, specifically, for DK Metcalf, but then they traded George Pickens, essentially a swap of 1s. Where we should see more differences, though, is schematically.
