Pittsburgh’s defense enters a window of heightened expectation. Mike Tomlin’s bold optimism underscores a unit rebuilt to stop the run and sharpen back-end communication after a troublesome finish to 2024. The influx includes Darius Slay, Jalen Ramsey, Juan Thornhill, Chuck Clark and Brandin Echols, joining a defensive core led by T.J. Watt and Cam Heyward with Patrick Queen in the mix. Ramsey’s role as a multifaceted striker at free safety has already yielded an early highlight, and Metcalf’s praise of the defense adds a level of respect from a firsthand rival. Aging stars on the Steelers, including Heyward at 36, add a caveat about longevity, even as Harmon, Black and Sawyer push to prove themselves. Tomlin’s history of dominant defenses, from his Buccaneers stint to Pittsburgh’s early-season excellence, provides a blueprint, but skepticism remains about the 30-plus group’s ability to sustain a historic run. The potential payoff is a defense that could redefine Pittsburgh’s ceiling, possibly even sparking a long-awaited playoff breakthrough if the scheme and communication click under pressure.
