Former Steelers Star Fully Explains How Mike Tomlin Cost Pittsburgh A 7th Super Bowl

The Pittsburgh Steelers are going through a major transition heading into the 2026 season, moving from Mike Tomlin to Mike McCarthy at the head coaching position. For McCarthy, it's crucial to come in and help end the playoff drought that has plagued the organization since the 2017 NFL season. The last time the Steelers underwent a coaching change, transitioning from Bill Cowher to Tomlin, there also was an adjustment period.

However, that move eventually culminated in a Super Bowl victory during the 2008 season, just two years after Tomlin was hired. Many critics still argue that Tomlin won that championship with a roster largely built by Cowher.

When Tomlin took over in 2007, he wanted to establish himself immediately. As a relatively unknown head coach at the time, he believed earning the respect of veteran players was essential. Tomlin pushed the team hard, implementing demanding training camp schedules that included two-a-day practices and intense offseason workout programs. That level of intensity carried over into the regular season as well.

As it turns out, and as has been the case throughout professional sports history, the line between keeping players sharp and overworking them can be incredibly thin. In this case for Tomlin, it was his first season and he was still learning how to operate offseason and in-season programs. 

According to former Steelers star James Harrison, Tomlin crossed that line during his first season. Harrison later suggested via his Deebo & Joe podcast that the team was pushed too hard, leaving players worn down at the wrong time and potentially costing Pittsburgh an opportunity to make another Super Bowl run.

"We lost a couple starters, things changed, Coach [Bill Cowher] was gone," Harrison said Monday during his time speaking on his podcast. "We lost Joey [Porter]. I replaced Peezy, and it was maybe one or two other people, but we still had that core group together. The thing that happened when Mike Tomlin came in, he didn't change nothing. We kept the same defense, so all we did was put the players into the spot."

As Harrison explains it, Tomlin inherited a roster that was largely built by Cowher. While a few players had to be replaced, Harrison's belief is that the core of the team remained intact and that Tomlin did not make any significant changes upon taking over.

Despite entering the postseason with high expectations, the Steelers were eliminated in the AFC Wild Card Round, suffering a shocking 31-29 loss to the Jacksonville Jaguars at then-Heinz Field. 

Looking back on that season, Harrison believes Tomlin's demanding approach ultimately played a role in the defeat. In Harrison's view, the team was overworked throughout the year, leaving players exhausted by the time the playoffs arrived and costing Pittsburgh a legitimate chance to win another Super Bowl.

"We should've won the Super Bowl again that year, but we got drove so hard in training camp and through the season that we ended up losing to Jacksonville at home...I feel like we could've did it then. We [got] ran into the dirt from training camp all the way through that we didn't have it to finish."

Steelers Enter Into A New Era Under McCarthy

Now the Steelers are in a similar situation, but not the same one. McCarthy was not hired as a relative unknown, but he operates very differently from how Tomlin did. Steelers fans are entering a new era and are eager to see how it unfolds. 

Hearing stories from former players about the Tomlin era only adds more weight to this next chapter of the franchise.
