After Rooney emphasized a return to Pittsburgh's smashmouth roots a half-decade ago, pass-happy coordinator Bruce Arians was sent packing.
When Rooney expressed concern for Ben Roethlisberger's health, draft picks were devoted to the offensive line while coaches worked with the quarterback to get rid of the ball faster.
As the Steelers embark on the 2016 offseason, Rooney has identified the porous secondary as the priority.
"If you look at us statistically, we weren't where we'd like to be in terms of pass defense, and so that's an area we know we want to improve upon," Rooney said, via the team's official website. "We certainly made progress on defense. We got better as the year went on, but we all agree we need to be better in general as a pass defense.
"I'm not going to suggest we need to do something dramatically different. We invested some draft picks in some players last year we certainly hope are going to take a step forward this coming season and be contributors. Obviously we have some opportunities this offseason in terms of free agency and the draft. It's something we have to keep working on."
If general manager Kevin Colbert shores up that leaky secondary, we could be discussing Roethlisberger as an MVP candidate next season.
