The Pittsburgh Steelers have invested heavily in their defensive front, and new head coach Mike McCarthy isn’t hiding his expectations for the group entering the 2026 season. In fact, McCarthy believes Pittsburgh’s defensive line has the potential to be one of the defining strengths of his first Steelers team.
“I love everything about the D-line,” McCarthy said Monday as the Steelers began preparations for their Week 1 matchup with the Atlanta Falcons. “This D-line is as deep a group as I’ve been a part of.”
That’s quite a statement from a coach who has spent more than three decades in the NFL, but McCarthy went one step further. “Thinking back over the last three decades, it’s a group that I look to carry the team,” he added.
McCarthy sees the trenches as part of Pittsburgh’s identity
McCarthy’s praise wasn’t limited to the talent or depth of Pittsburgh’s defensive line. He connected the importance of winning up front with the style of football he believes the Steelers need to play, saying, “O-line and D-line this part of the country, this style of play, you’ve got to have it, and we’ve got it. I’m excited about our D-line.”
It’s a philosophy that should sound familiar to Steelers fans. Pittsburgh has traditionally built some of its best teams around controlling the line of scrimmage, particularly on defense, and McCarthy clearly sees the current group as capable of continuing that tradition.
More importantly, this isn’t simply a matter of having a few established players at the top of the depth chart. McCarthy specifically singled out the depth of the entire unit as one of its greatest strengths.
Defensive coordinator Patrick Graham didn’t hesitate when asked whether Pittsburgh could lean on its front seven, either. With some uncertainty surrounding the secondary entering Week 1, Graham acknowledged that the experience and talent Pittsburgh possesses up front will play an important role in how he approaches his defense.
“Naturally from my standpoint as the defensive coordinator, I’m going to lean into it when you have players up front such as T.J. [Watt] and Cam [Heyward] as leaders, in terms of just what they’ve done over their career and how hungry they are,” Graham said. “I’m amazed at some of the stuff they do in practice, just the way they go about their business, the way they talk football.”
Graham plans to let Steelers’ front play
Watt and Heyward give Graham two established leaders to build around, but they’re hardly alone. Graham also pointed toward Alex Highsmith, Derrick Harmon and Yahya Black when discussing the players Pittsburgh has surrounding its veteran stars.
“There’s a lot of guys that have played some really good football,” Graham said. “Part of my job is to make sure to put them in the right spots, make sure we’re not doing too much. That’s the one thing that – just to let them play football.”
That approach fits particularly well with Graham’s defensive background. While communication and the ability to adjust are major parts of the system he’s installing in Pittsburgh, Graham described himself as “more of a front guy” and said his defenses throughout his career have been largely driven by what happens up front.
“Everything for me in my career has been mostly front driven,” Graham said. “So, I would think it’s a safe bet to think that I’m going to lean into it a little bit more.”
Put McCarthy’s and Graham’s comments together and the expectations become fairly clear. Pittsburgh isn’t merely hoping its defensive front develops into a strength over the course of the season. The Steelers are preparing to lean on it immediately, with their veteran stars leading a deeper group behind them.
Steelers’ depth blends veterans with young talent
The mixture of established players and developing talent also fits into McCarthy’s larger philosophy for constructing his first Steelers roster. Pittsburgh retained its entire rookie class following roster cuts, a decision McCarthy said came down first and foremost to those players earning their opportunities.
However, he also acknowledged the financial realities that make developing younger players essential in today’s NFL. “This is a young league, and I think that’s an important part of growth and development,” McCarthy said. “You can only pay so many people, so youth is important as far as the makeup of your roster.”
That philosophy extends beyond simply keeping young players on the roster. McCarthy said the Steelers hold meetings specifically for their younger players at 7 a.m. on Wednesday, Thursday, Friday and Saturday as part of an ongoing effort to accelerate their development. He described his coaching approach as “teaching to the youngest player in the room,” while utilizing Pittsburgh’s veteran players to help bring those younger teammates along.
That dynamic is particularly visible along Pittsburgh’s defensive front. Watt and Heyward have years of NFL experience to draw upon, while players such as Harmon and Black give Graham younger pieces to develop and incorporate into the rotation. McCarthy believes that combination has created unusual depth, while Graham sees an opportunity to take advantage of it without unnecessarily complicating what those players are asked to do.
Atlanta will test Pittsburgh’s defensive front immediately
The Steelers won’t have to wait long to find out how well that approach works. Atlanta presents an immediate challenge for Pittsburgh’s front, particularly because of a running game led by Bijan Robinson and an offense McCarthy and Graham both believe does a good job of creating conflict for opposing defenses.
McCarthy specifically pointed toward Falcons head coach Kevin Stefanski‘s ability to marry the running and passing games, including the use of outside zone concepts and the play-action opportunities that develop from them. Graham similarly praised Stefanski’s commitment to the run while noting Atlanta’s talent along the offensive line and at the skill positions.
Graham has faced Robinson before and didn’t need statistics to explain the challenge Pittsburgh will face Sunday.
After watching Robinson’s more recent film, the Steelers defensive coordinator called him a “special, special football player.” He also noted the presence of Brian Robinson behind him, giving Atlanta another running back Pittsburgh will have to account for.
Containing that backfield will put McCarthy’s lofty assessment of his defensive line to an immediate test. Pittsburgh’s front will need to remain disciplined against an offense capable of building play-action and movement off its running game while also winning enough individual battles to keep Atlanta from controlling the game on the ground.
McCarthy believes the Steelers have the depth to do it, and Graham clearly intends to lean on the group. After more than 30 years of coaching in the NFL, calling this one of the deepest defensive lines McCarthy has ever been around is significant praise. Saying he expects the unit to help carry the Steelers makes the expectations even clearer as Pittsburgh prepares to open the 2026 season.
