The battle between the Pittsburgh Steelers' defensive front and the Cincinnati Bengals' offensive line has long been the primary storyline in this heated AFC North rivalry.

Historically, T.J. Watt and Pittsburgh's pass rushers have dominated the matchup. However, broadcaster Cris Collinsworth highlighted a major shift in momentum ahead of their upcoming Sunday night rematch. He noted that Cincinnati's pass protection has dramatically improved over the last month.

That evolution fundamentally changes how the Steelers must approach their pass rush.

"We've never seen anything like the last month what these guys are doing," Collinsworth observed during the game preview. "And one of the keys I think is the way the offensive line has improved. That has always been an issue, especially against T.J. and the Pittsburgh Steelers, because that's exactly what it's going to come down to."

In previous years, Pittsburgh relied heavily on winning quick individual matchups up front to disrupt Cincinnati’s offensive rhythm. When the Steelers edged out a 30-27 victory in Week 3, the battle in the trenches set the tone for a down-to-the-wire divisional thriller. But with Joe Burrow operating behind a far sturdier pocket during Cincinnati’s current four-game winning streak, the workload falling on Pittsburgh's front four has doubled.

Rather than relying on schematic tricks, Pittsburgh's defensive line must beat improved protection cleanly. Former Steelers head coach Mike Tomlin acknowledged that the game hinges on whether Watt and company can win their four-on-five battles against an offensive line that is no longer the liability it once was.

As Collinsworth noted, the outcome won't be dictated by Cincinnati's ground game, but rather by whether their protection can withstand Pittsburgh's star edge rusher. For the Steelers to sweep the season series, their pass rush must overcome a newly fortified offensive line.
