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.

Be the Referee: Volleyball Libero Uniforms

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.
