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.

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.
