Be the Referee: Coaching Box Expansion

December 6, 2018

This week, MHSAA officials coordinator Sam Davis details the adoption of the larger sideline coaching box for basketball.

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 – Coaching Box Expansion - Listen

There’s one very visible change coming to the basketball court this year in Michigan. The sideline coaching box has been expanded from 14 feet to 28 feet. The expansion was allowed by national playing rules for individual state association adoption a year ago, but the change was announced too late for Michigan to opt for the larger box.

Even though the box size has changed, other rules for behavior inside the box have not. Only the head coach is allowed to stand up in the box as allowed by rule; once the coaching box is lost due to a technical foul, there is no way to get the coaching box back; and all other related rules restrictions apply.

The change brings the game in Michigan full circle from when the old “seat belt” rule was created in the 1980s. Hopefully, common sense will prevail, and the coaching box will be used for just that – coaching.

Officiate Michigan Day 2026 will welcome more than 1,000 Michigan High School Athletic Association-registered game officials July 25 to DeVos Place in Grand Rapids, where they will receive knowledge and instruction from several high-profile voices headlined by recent National Soccer Hall of Fame inductee Kari Seitz – a Brighton High School graduate – and one of television’s most recognizable rules analysts, Mike Pereira.

Officiate Michigan Day is designed to benefit officials with any level of experience, veteran to beginner. High-profile clinicians representing several sports and all levels including the NFL, NBA, MLB, NCAA, FIFA and the National Women’s Soccer League (NWSL) will provide face-to-face training during four sport-specific breakout sessions throughout the conference.

Pereira, a past collegiate and NFL football official who also has served as the NFL’s vice president of officiating, will present the opening address at 9 a.m. He has provided his knowledge during FOX Sports football broadcasts since 2010, explaining rules scenarios on-air as situations unfold in-game. 

Seitz, also a graduate of Michigan State University, refereed Women’s World Cups in 1999, 2003, 2007 and 2011 and Olympics tournaments in 2004, 2008 and 2012, and will deliver the conference’s closing message. She’s currently the vice president of refereeing for U.S. Soccer and formerly served as FIFA’s heading of refereeing.

This will be the third Officiate Michigan Day, joining events in 2013 and 2018. OMD 2026 will accompany the annual National Association of Sports Officials (NASO) Summit that will take place July 26-28, also at DeVos Place.

Officials may continue to register on the Officials page. Cost is $50. Additional details, including the full lineup of speakers and clinicians, also is available at that link.
