In 2025, the Pittsburgh Steelers’ offensive line made big strides. The franchise’s investment in the trenches finally began to pay off. Zach Frazier is a Pro Bowl-caliber center. Troy Fautanu showed why he’s a former first-round pick. Mason McCormick settled in at right guard. Broderick Jones improved, while Dylan Cook could enter 2026 as the starter, and Isaac Seumalo was the steady veteran.

The group passed the eye test. They also passed the penalty test. Pittsburgh’s offensive line played incredibly clean football for an entire season. Using the handy website NFL Penalties, we can track the Steelers’ numbers in relation to the rest of the league.

Collectively, Pittsburgh’s main starters received just eight flags. The entire offensive line was called for just 13 infractions. Here’s the player breakdown.

Offensive Lineman Penalties

Isaac Seumalo – Zero
Broderick Jones – One (holding)
Dylan Cook – One (false start)
Mason McCormick – One (false start)
Troy Fatuanu – Two (one holding, one false start)
Zach Frazier – Three (two holding, one false start)

Spencer Anderson was flagged twice, and Andrus Peat was penalized three times. It’s worth noting that a would-be third penalty on Fautanu, a holding, was declined.

That in itself is impressive. But like any data point, it’s important to stack it up to the rest of the NFL. Pittsburgh continues to shine. Here are the penalties and yardage for all accepted flags along the offensive line, via the previously referenced NFL penalty website.

Pittsburgh easily ranks the best. Not just in total penalties, but in penalty yards as well, with 92. The Steelers are the only team to be under 100 yards, with the second-place Los Angeles Rams amassing 32 more penalty yards than Pittsburgh.

The Los Angeles Chargers and New Orleans Saints were the worst offenders. They had more than triple the offensive line penalties and nearly triple the yards.

Some penalties are subjective. Sometimes, a lineman gets away with a call. Sometimes, he gets called for a ticky-tack play. Still, those things tend to come out in the wash over a 17-game season. For such a young offensive line playing with a veteran quarterback, the unit’s cleanliness is remarkable. Rodgers’ cadence is a weapon, and Pittsburgh’s offensive line held its water with just four false starts all season.

Avoiding these penalties helped avoid negative plays that often ruin drives. A false start on third down can change the complexion of the conversion. A holding call that creates 1st and 20 often ends any chance of the possession being successful. No group avoided those pitfalls better than Pittsburgh, which will remain its mission in 2026 under the new coaching staff.
