The Steelers advanced to 11-0 on Wednesday despite an uninspiring effort against the shorthanded Ravens.

Pittsburgh squandered multiple red zone trips and muffed a punt in its 19-14 win. It also nearly blew a late 12-point advantage, needing a tough catch from James Washington in traffic to prevent Baltimore from getting the ball back with the chance to take the lead in the final two minutes of regulation.

As expected, the Ravens offense struggled without Lamar Jackson, Mark Ingram, J.K. Dobbins or Willie Snead IV. Before a 70-yard touchdown grab by Marquise Brown with 2:58 to go, the depleted group, which subbed in quarterback Trace McSorley for Robert Griffin III in the fourth quarter, managed just 40 passing yards.

It was surprising, then, that the Steelers never managed to pull away. Should they continue to make the mistakes they made against Baltimore, their undefeated mark won’t last much longer.

Coach Mike Tomlin used the term “unacceptable” multiple times in his postgame news conference to describe his frustration.

“We didn’t play well or coach well tonight,” Tomlin said.

Mike Tomlin isn’t one for excuses. Even as COVID-19 wreaked havoc with his team’s schedule, pushing their matchup with Baltimore from Thanksgiving night to middle of the afternoon in the middle of the week in the middle of a pandemic, the longtime Pittsburgh Steelers coach refused to reach for one.

So while the Steelers stayed perfect with a disjointed 19-14 win over the undermanned Ravens in the first NFL game on a Wednesday in eight years, their play was anything but. And Tomlin knows it.

“To be bluntly honest, I’m really disappointed in our performance tonight,” he said after Pittsburgh improved to 11-0. “We did enough to win tonight, that’s all.”

Calling it “junior varsity”-level play, Tomlin seethed in the aftermath, a testament to both how high the bar is set and just how far the Steelers came from clearing it.

Asked about an offense that managed just one touchdown in four trips to the red zone — missed opportunities that allowed the Ravens (6-5) to hang around until the final minutes — Tomlin didn’t offer analysis as much as rage.

“Us sucking,” he said, declining to get into specifics.
