The Pittsburgh Steelers spent the spring learning what their first-round rookie looked like in helmets, shorts and controlled drills. Training camp supplied the part of the evaluation that actually interests offensive line coaches. Once the pads came on, the question stopped being how Max Iheanachor moved through practice and became whether he could hold up when NFL veterans were allowed to hit back. Mike McCarthy believes the rookie has already cleared that first important line.

There was always going to be a difference between Iheanachor looking athletic in the spring and looking like an NFL tackle in August. The Steelers selected him 21st overall because his movement, frame and upside gave them a long-term answer worth developing. They also knew his football résumé was shorter than most first-round linemen, making padded work a much more useful checkpoint than another clean rep against air.
Pads are football’s version of a lie detector for offensive linemen. Everybody can look coordinated before a defender is trying to put 270 pounds through his chest. Iheanachor needed to show that the traits Pittsburgh saw on college tape could survive contact, speed and veteran pass-rush tricks.
That is what sent McCarthy back to the rookie’s Senior Bowl film. Pittsburgh’s head coach said Iheanachor’s first padded work reminded him of the week that helped push the tackle up the Steelers’ draft board.
During his training camp media availability, McCarthy explained why the switch to pads changed his evaluation.
“When I watched him the first day in pads, I kind of went back to the Senior Bowl tape,” McCarthy said. “It’s that threshold of the padded work, the competition with the veterans, and he definitely crossed the line now… He has a lot of work, but frankly, our whole team has a lot of work to do.”
McCarthy did not declare the right tackle competition over. Crossing the threshold means Iheanachor has shown he belongs in the conversation when the football becomes physical. It does not mean the rookie is suddenly a finished starter.
Dylan Cook entered camp with the first-team offense and has done nothing to make Pittsburgh hand the job away. Cook has game experience and offers the stability a win-now team can appreciate. Iheanachor’s job is to make the ceiling he offers more valuable than the comfort Cook provides.
The rookie has started doing that in padded practices. Reports from camp have highlighted his run blocking and ability to hold his own against established edge defenders. That is a meaningful step for a tackle whose developmental questions have centered more on technique and experience than physical ability.
Pittsburgh can also give him one of the least forgiving classrooms in football. TJ Watt, Alex Highsmith and Nick Herbig can show a rookie almost every version of trouble an NFL tackle will see. If Iheanachor’s hands are late or his balance disappears, someone in that group will usually provide the correction before an offensive line coach needs to open his mouth.
That environment makes his expected rookie timeline more interesting. Pittsburgh entered camp with no need to rush him. Cook could start while Iheanachor developed behind him. Each strong padded practice gives James Campen another reason to reconsider how long that arrangement needs to last.

The rookie still has technical work ahead. NFL pass rushers will attack the same weakness until he proves it has disappeared, and natural power cannot rescue every bad hand placement or late step. McCarthy’s praise confirms the project is moving, not that the project is complete.
His current injury interruption adds another wrinkle. Iheanachor left Thursday’s practice early with an undisclosed issue, and McCarthy said Friday that he is expected to remain out until Monday. A few days should not erase what the staff saw once the pads came on, but missed camp reps are expensive for a rookie trying to close a gap on a veteran.
The timetable gives Pittsburgh room to be patient. If Iheanachor returns Monday as expected, the right tackle competition can resume without turning a minor August interruption into something larger. The Steelers drafted him for years, not for one practice in Latrobe.
Steelers Can Let The Pads Make The Decision
The easiest mistake Pittsburgh could make is allowing draft status to decide the lineup. Iheanachor being the 21st pick guarantees attention, not a starting job. Cook has to be beaten through better football, and padded practices are where the rookie finally gets to make that argument honestly.
McCarthy’s return to the Senior Bowl tape is a useful sign. The Steelers liked Iheanachor because he elevated himself when the competition became more serious during the pre-draft process. Training camp is beginning to show the same pattern. The uniform got heavier, the defenders got better and the rookie looked more convincing.
That does not require Pittsburgh to accelerate everything at once. Campen can keep drilling the footwork, hand placement and recognition that will determine whether Iheanachor survives on Sundays. Cook can keep taking first-team reps. The rookie can keep forcing the coaches to revisit the depth chart.
For a developmental tackle, that is what progress should look like. The spring gave Pittsburgh reasons to be intrigued. The first padded work gave McCarthy something stronger: evidence.
Iheanachor still has plenty to learn, and his brief injury pause will delay the next part of the test. Once he returns, the equation is simple. If the rookie keeps looking better as the football gets more physical, Pittsburgh may not be able to keep calling him a future answer for much longer.
