Pittsburgh has been to the playoffs in two of running back Najee Harris’ three seasons with the Steelers.

Pittsburgh’s latest postseason trip ended the way its previous three did – one-and-done. The Steelers lost to the Buffalo Bills 31-17 on Monday to end their 2023 season.

For Pittsburgh to progress past that point, Harris said the Steelers need to change their “in-house rules.”

“Just the rules that are in the building,” Harris said. “We got to be more disciplined. We got to be more committed. I’m not saying that we’re not, but just coming from a place that has structure and just seeing we probably could get help in these areas if we might make a change. I think that that’s something we could help. I’m not saying nothing about coaches or anything like that. I’m just saying more of just in-house rules. That’s all I’m saying.”

What “place that has structure” did Harris come from?

The running back joined Pittsburgh as a first-round selection from Alabama in the 2021 NFL Draft. A two-time 1,000-yard rusher for the Crimson Tide, Harris earned unanimous All-American recognition, won the Doak Walker Award as the nation’s best running back and set an SEC single-season touchdown record for Alabama’s unbeaten CFP national-championship team in 2020.

“I have my opinions on things, but I’m just a player,” Harris said. “But if you want to elevate and get where we’re, there’s got to be some in-house things that needs to change, I feel like. Coach (Mike Tomlin) always tells me just to play running back. That’s a little inside thing that we have, too. But if you want to elevate and get where we are and achieve those goals that we want, we have to change some in-house stuff. But, like I said, that’s not my place, that’s not anything I control or anything I can do about that.”

If that explanation leaves questions about what exactly he is referring to, Harris said, “The guys in that building know what I’m talking about.”

Pittsburgh qualified for the postseason by winning its final three games, with Harris rushing for 312 yards and four touchdowns on 72 carries in those contests. But he had only 12 carries for 37 yards against Buffalo.

By the time the Steelers offense snapped the football for its 10th time on Monday, Pittsburgh trailed 14-0.

The late surge allowed Harris to become the 18th player in NFL history to run for 1,000 yards in each of his first three seasons.

The Steelers face a decision on Harris this offseason, when they can exercise their fifth-year option on his four-year, $13.047 million rookie contract. If Pittsburgh picks up its option, it will guarantee Harris a payday of an estimated $6.659 million for the 2025 season. If the Steelers don’t use their option, Harris would be headed toward free agency after the 2024 season.
