Before Mike Macdonald walked onto the field for Super Bowl LX, he had one more conversation to have. The Seahawks coach reached out to John Harbaugh, the man who had hired him as a 26-year-old intern in Baltimore and watched him climb from the bottom of the staff to defensive coordinator. Macdonald had since left the Baltimore Ravens, built his own team in Seattle, and reached the biggest stage in football. Their relationship had changed, too, but it clearly hadn’t disappeared. 

 While leaving Baltimore, Macdonald had wondered whether he was good enough without Harbaugh. Two years later, the first of which ended 10-7, good for second in the NFC West but not a playoff berth, he was finally a Super Bowl-winning head coach. But if you ask him, he will tell you the move was anything but easy.

“I worked for 10 years for him; gave an honest decade of work for him and his brother,” Macdonald said on In Depth with Graham Bensinger. “I love him. I love his family. You tell me I got to work for Jim and John Harbaugh- I’m like one of four people that ever got to say that just really I take a lot of pride in that.

“I think actually that was an area of growth for me was making the Seahawks team, in my identity and true to me. I actually remember almost feeling- coach the defense in the image of the way John wanted his football team…And it actually kind of hurt me because when I went from Baltimore to Seattle, I was like John’s guy that now doesn’t have John anymore. And so it’s like where does that where am I going to go? Is Mike Macdonald good enough? I remember thinking having doubt in that.”

Mike Macdonald spent nine seasons under John Harbaugh in Baltimore, though not nine seasons in a row, and that gap matters. He started off as an intern with the Baltimore Ravens in 2014, then climbed to defensive assistant (2015-2016), backs coach (2017), and linebackers coach (2018-2020). In 2021, he left. Not for Seattle, for Ann Arbor.

Jim Harbaugh, John’s younger brother, hired him as Michigan’s defensive coordinator, making Macdonald one of a small handful of coaches who has worked for both Harbaughs. It turned into one of the better seasons of his career on either level: Michigan went 12-2, won the Big Ten, beat Ohio State 42-27, and made the College Football Playoff for the first time in program history.

John brought him back to Baltimore in 2022, this time straight into the defensive coordinator’s chair. When the Ravens rehired him, Harbaugh called him “a Raven through and through” and said his intelligence and leadership had made an NFL coordinator job feel inevitable. For the next two seasons, Harbaugh supervised Macdonald directly as his head coach. So, naturally, the Seahawks’ current head coach has credited Harbaugh for his professional growth.

“I don’t think it’s possible to overstate his influence on me,” Macdonald said earlier this year. “I love John Harbaugh. He’s one of my biggest mentors. He was willing to take chances on me when other people weren’t and invested in me throughout my career. He had a vision for me and my career that I probably didn’t have for myself… I can’t say how much I love him.” He added: “Those are a lot of the foundational principles that we brought to Seattle.”

After nine seasons across two stints with Harbaugh’s Ravens, Mike Macdonald left again, this time for good, to become the head coach of the Seattle Seahawks in January 2024. Unlike his moves to Michigan and back to Baltimore, this one didn’t come with a built-in staff. Most of his coaching network was concentrated around one organization, so GM John Schneider and Macdonald had to assemble a staff from scratch, fast. Macdonald has said he prioritized finding the best teachers for the job over simply importing people he already knew from Baltimore. And Macdonald didn’t take much time to showcase his learnings as the HC.

In his debut season, Macdonald finished 2nd in their division with a record of 10-7. A season later, Seattle won the NFC West, then the NFC championship, then Super Bowl LX against the New England Patriots. Asked that year how he’d built the Seahawks’ identity, Macdonald described leaning on a “blueprint” of what had worked for him before, “with tweaks”, rather than simply copying what he’d run in Baltimore.

Harbaugh was immensely proud of Mike Macdonald’s success as head coach. When the two ran into each other shortly at the NFL Scouting Combine earlier this year, Harbaugh greeted Macdonald with a “big hug” and jokingly told reporters:

“It was a big hug, congratulations, and he’s always smiles right now,” Harbaugh said of Macdonald. “I can’t imagine why. And well-deserved. Proud of Mike. One of my favorite people.”

That conversation from before the Super Bowl, the one that opened this story, surfaced months later. Asked in July on The Dan Patrick Show which piece of advice ahead of the game might surprise people, Macdonald didn’t hesitate: “John Harbaugh and I talked. He was great.” Six years after wondering if he was good enough without him, Macdonald was calling Harbaugh for advice as a Super Bowl head coach in his own right.

Their paths crossed again at the 2026 NFL Annual Meetings in Phoenix. Macdonald walked out of a ballroom after finishing one interview and found Harbaugh waiting outside for his own, by the Seahawks’ own account, Macdonald was caught off guard by it. They talked for a few minutes before Harbaugh got pulled away. No reunion, no occasion for it, just two coaches who happened to be in the same hallway again.

Then, at the Combine, Harbaugh said something that turns the whole story over. Talking about Seattle’s title-winning roster, he said he’d been studying the team Macdonald had built, Macdonald, Leslie Frazier, and Jay Harbaugh (John’s nephew, Jim’s son, and Macdonald’s special teams coordinator, carried over from his Baltimore and Michigan staffs) among them, and that watching what they’d put together was shaping his own thinking about the team he wants to build in New York.

The man who once wondered whether he was good enough without Harbaugh in his corner is now someone Harbaugh is taking notes from. That’s not Macdonald outgrowing his mentor so much as it is a decade of borrowed lessons getting rebuilt into something that belongs to somebody else.
