UNITY TWP, Pa. — Entering his 16th season in Pittsburgh, Cam Heyward remains the heart and soul of the Pittsburgh Steelers defensive line. But as training camp unfolds, the veteran team captain's most impactful work might be taking place between reps, passing the torch to the franchise's next generation of trench monsters.
At the center of Heyward's mentorship are second-year defensive linemen Yahya Black and Derrick Harmon . Both saw meaningful action as rookies in 2025, but with the 2026 campaign looming, the time for developmental leeway has officially expired. Heyward isn't letting them forget it.
Speaking after a physical team session, Heyward lauded the growth he has seen from Black, who added weight this offseason and has pushed his way into the starting nose tackle role.
"He looked good today," Heyward said. "He's using his hands a lot better coming out of his hips. He's got to be a player for us. Him and D-Harm can no longer be rookies."
Harmon, a 2025 first-round pick who earned the team's Joe Greene Great Performance Award despite battling knee trouble throughout his debut season, is primed for a massive sophomore leap alongside Black. For Heyward, the physical tools were always there, but the transition from thinking to reacting is what elevates good players into game-changers.
"I mean, you've got to look for him to take a step in year two," Heyward noted. "It's not just they're thinking, they're playing with good energy, making plays in the backfield."

With new defensive line coach Domata Peko raising expectations and Heyward setting the daily standard, Pittsburgh's defensive front is aiming to re-establish its trademark dominance against the run. Heyward knows that keeping the defense elite requires every rotational piece to step up in unison.
"It's not just one guy," Heyward said. "It's a group of guys that are just growing in this."
If Black and Harmon continue their upward trajectory under Heyward's wing, Pittsburgh's front seven looks ready to terrorize opposing offenses all season long.
