For a combined 29 seasons, Mike Tomlin and John Harbaugh have presided over two of the NFL's most successful franchises. Tomlin has led the Pittsburgh Steelers to one Super Bowl win, two AFC titles and seven division titles since succeeding Hall of Fame coach Bill Cowher in 2007. Harbaugh has guided the Ravens to one Super Bowl title and five division titles since going to Baltimore in 2008. 

The longtime head coaches will make NFL history when Pittsburgh hosts Baltimore this Sunday at Heinz Field. The game will mark the 30th meeting between the two coaches, marking only the third time in league history that opposing coaches have met at least that many times, according to's Missi Matthews. Former Bears coach George Halas faced former Packers coach Earl "Curley" Lambeau 49 times during their Hall of Fame careers, with Halas' Bears posting a 30-16-3 record. Former Giants Hall of Fame coach Steve Owen faced Lambeau 31 times, with New York going 15-14-2 in those matchups. Tomlin's Steelers are 15-14 against Harbaugh's Ravens. 

Here's a look at some of the highlights during the first 29 matchups between the two coaches. 

  • Tomlin holds a 2-1 postseason record vs. Harbaugh. Pittsburgh beat Baltimore in the 2008 and 2010 postseasons before the Ravens defeated the Steelers in the 2014 wild-card round. 
  • Baltimore's longest winning streak over Pittsburgh is four games spanning from January 2015 to November 2016. The Steelers' longest winning streak over Baltimore under Tomlin is three games, which has happened on two separate occasions, the most recently taking place from 2016-17. 
  • Under Tomlin, Pittsburgh swept Baltimore in 2008 and in 2017. Harbaugh's Ravens swept the Steelers in 2011, 2015 and 2019. 
  • The Steelers' largest margin of victory over the Ravens under Tomlin was 20 points in Week 9 of the 2014 season. The Ravens' largest margin of victory over the Steelers under Harbaugh was 28 points in Week 1 of the 2011 season. 
  • Of their first 29 meetings, 21 of those games were one-possession outcomes, inducing seven of the first eight matchups. 
  • In 2020, the duo became the first pair of coaches to face each other in the regular season 25 times in the Super Bowl era. 

Despite their teams' intense rivalry, Tomlin and Harbaugh have a mutual respect for one another. 

"They stay true to themselves, and that's what they're all about," Harbaugh said of Tomlin's Steelers last fall, via ESPN's Jamison Hensley. "So, that's a mark of a heck of a coach, and obviously coach Tomlin is one of the best, and we have great respect for everything they do."

"You know what the Ravens games are about," Tomlin said of Harbaugh's Ravens. "They are a top-notch organization and football team. They have talent across the board. They're familiar with us. We're familiar with them. There's continuity within schematics and both staffs and core players and things, and I think that's what adds to the intrigue. We should anticipate it being a physical and rough-and-tumble game because history tells us that, and how the two teams are playing this year also gives you that indication."
