Be the Referee: Blocking Below the Waist

November 13, 2014

This week, MHSAA assistant director Mark Uyl explains the differences between high school and the college and professional games when it comes to blocking below the waist.  

"Be the Referee" is designed to help educate people on the rules of different sports, to help them better understand the art of officiating and to recruit officials. The segment can be heard on Mondays, Wednesdays and Fridays during the school year on The Drive With Jack Ebling on WVFN-AM, East Lansing.

Many times the key rules differences between high school football and those rules used at the college and profession levels deal with player safety. One of the best examples of this deals with the rules that cover blocking below the waist.

All of us have watched that game played on Saturday or Sunday; we’ve seen that wide out or the wide receiver blocking downfield, and they block the defender below the waist in springing that runner for a big gain.

At the high school level, the only offensive players that can block below the waist are those on the offensive line, generally positioned from tackle to tackle, and those blocks below the waist must be immediate – at the snap – and within that free blocking zone at the line of scrimmage.

Be the Referee: Basketball Measurements

By Sam Davis
MHSAA Director of Officials

January 4, 2023

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 – Basketball Measurements - Listen

If you’ve seen the movie “Hoosiers,” you know that a basketball rim is 10 feet above the ground. That’s the same if you are in the gym at Beaver Island High School or at Little Caesars Arena. But what are the other court dimensions?

To start – courts are typically 84 feet long but can be up to 94 feet long. They are 50 feet wide.

The free throw line is 15 feet from the face of the backboard and the high school 3-point line is 19 feet, 9 inches from the basket.

Each hoop is a circle, 18 inches in diameter.

The boys play with a basketball 29½ inches in circumference, the girls with one 28½ inches in circumference.

And believe it or not, two girls balls will go through a standard rim at the same time.
