What's My Why: Official Kari Seitz

August 19, 2026

Kari Seitz, Mill Valley (Calif.)

Kari Seitz – the closing speaker at July’s Officiate Michigan Day in Grand Rapids – was one of the top American professional soccer referees and one of the most experienced female referees in the world. She is currently the vice president of refereeing for US Soccer and formerly served as the FIFA head of refereeing.

She worked four FIFA Women's World Cup tournaments (1999, 2003, 2007, and 2011), as well as three Olympic soccer tournaments (2004, 2008, and 2012), and is the only referee – man or woman – to officiate that many of both. Kari was inducted into the National Soccer Hall of Fame in 2026 and is a graduate of Brighton High School and Michigan State University.

So I was a soccer player, played soccer since I was 6. And at some point, I joined an all-girls travel team – that never happened. This was a long time ago.

Our coach required us together, every person on the team, to take the (officiating) course. Now, I believe he didn’t know anything about soccer. He was one of those parents who was reading it from a book and just cared about his kids. So he forced us all to take the referee course, and that altered the path of my life.

Be the Referee: Clipping Clipped

August 25, 2016

MHSAA assistant director Mark Uyl opens a new year of “Be the Referee” by explaining the latest rules change affecting blocking in football.

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – Clipping in the Free Blocking Zone - Listen

Most of the recent rules changes in high school football have all dealt with increasing player safety. The most significant change for the 2016 season focuses on safety, especially for offensive and defensive linemen.

For many years, the free blocking zone (the area between the two offensive tackles) was an area where two types of blocks – blocks below the waste and clipping, that are illegal on other parts of the field – were legal if done by linemen initially at the start of a play. For this season, clipping is now an illegal block, even in the free blocking zone, while blocks below the waste continue to be legal from in front.
