Katherine Sowers on Coaching, Breaking Barriers, and What Flag Football Needs Next

When Katherine Sowers walked onto the field for Super Bowl LIV in February 2020, she became the first woman — and the first openly gay coach — to coach in a Super Bowl. It was the headline that introduced her to the world. But for Sowers, the moment was never the point. The work was.

That same work ethic is what she has carried into flag football, a sport she now sees as one of the most important growth engines in American football. We sat down with her for a wide-ranging conversation about coaching, barriers, and what the game needs to do next.

From the Super Bowl Sideline to the Flag Field

Sowers joined the San Francisco 49ers in 2017 through the Bill Walsh Diversity Coaching Fellowship, then earned a full-time job as an offensive assistant — a role she held through the 2020 season. The NFC Championship run that took the 49ers to Super Bowl LIV put her in the history books.

What is less widely known is what she did next. Between 2023 and 2024 she served as head coach of Italy's women's national flag football team, helping a European program punch above its weight on the international stage. She has also spent years building the women's flag program at Ottawa University, and she is set to join the University of Nebraska's women's flag football staff as associate head coach beginning in the 2027 season.

In other words: Sowers didn't treat flag football as a sideshow after the NFL. She treated it as the next frontier.

Building a National Program From the Outside

Coaching a national team that isn't your own country's is a unique challenge. You inherit a culture, a language barrier, and a player pool that may have come to the sport from completely different athletic backgrounds. Sowers' time with Italy's women's program was a lesson in adaptation — taking elite-level structure and translating it for athletes who were still defining what their national identity in the sport would be.

The lesson she keeps coming back to: you build a program by building people first. Systems matter, but belief matters more. A team that trusts its preparation plays faster, freer, and more fearlessly than one relying on raw talent alone.

What NFL Methodology Teaches Flag

It would be easy to assume that NFL coaching doesn't transfer cleanly to a five-on-five, no-contact game. Sowers sees it differently. The fundamentals of spacing, leverage, timing, and disguise are universal. What changes is the canvas.

In flag, the field is smaller and the margins are thinner. There is nowhere to hide a missed assignment. The discipline that defines pro football — film study, situational awareness, relentless attention to detail — is arguably even more decisive in flag, where a single broken coverage can end a game in seconds. Bringing that professional rigor to flag rooms is, in her view, one of the fastest ways to raise the ceiling of the sport.

The Coaching Pipeline for Women

Sowers is candid about the thing the sport still needs most: more women in coaching roles, at every level. Flag football has opened doors that tackle football kept closed for decades. Girls' high school participation is exploding, college programs are multiplying, and the women's game is growing faster than almost any sport in the country.

But players need coaches who look like them and who have walked the path. The pipeline she is helping build — from NFL fellowships to college staffs to national programs — is designed so that the next generation never has to wonder whether there is a place for them on the sideline. There is.

What Comes Next

With flag football headed to the 2028 Olympics in Los Angeles, Sowers believes the sport is at an inflection point. The talent is here. The infrastructure is catching up. What it needs now is investment — in coaching education, in youth development, and in giving international programs the resources to compete with the established powers.

Her message to anyone thinking about getting into the game, as a player or a coach: don't wait for permission. The sport is being built right now, in real time, by the people who show up. She would know. She has been one of them at every level.
