Be the Referee: Blindside Blocks

August 24, 2017

This week, "Be the Referee" with MHSAA assistant director Mark Uyl returns with the first of a three-part series on football rules changes for 2017, this one on blindside blocking. 

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 – Blindside Blocks - Listen


We're going to start the new school year with a three-part series on football rule changes.

There may be no hit in football that generates more "ohs" and “ahs" than the blindside hit. It's also one of the most dangerous hits in the game.

The defensive player in pursuit of the runner, who does not have a reasonable opportunity to see the oncoming blocker, is considered defenseless. In keeping with putting player safety first, national rules now allow blocking from the blindside only when contact is initiated with the hands – achieving the same effect without all the contact.

That big blindside hit will now result in a 15-yard penalty and possible ejection from the game.

Next week, we'll look at changes to rules covering onside kicks.

Be the Referee: Volleyball Libero Uniforms

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 – Volleyball Libero Uniforms - Listen

Before the match begins, a volleyball team takes the court wearing super-stylish, brand-new jerseys. The libero is in a bright neon top, but two other teammates also have the same neon sleeves.

At first glance, it looks like multiple liberos are on the floor. As the referee, you must check carefully: Under current NFHS uniform rules, the libero’s jersey must clearly contrast from all other teammates in color, design, and trim.

Accessories like sleeves or leggings are permitted, but they cannot confuse the identification of the libero. In this case, because the libero’s jersey color is the same as teammates’ sleeve color, the contrast is not sufficient, and the coach must correct it before play begins.

This ensures quick identification for substitutions, scoring, and libero actions.
