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.

Be the Referee: Defensive Holding

Below is this week's segment – Defensive Holding - Listen
Team A has the ball on their own 20-yard line and its 4th-and-15. They decide to go for it. The quarterback drops back to pass and is sacked at his 15-yard line, a five-yard loss.
But during the play, Team B – the defense – is flagged for holding an eligible wide receiver.
How is the penalty administered?
- Is it 4th-and-5 from Team A’s 30?
- Is it 4th-and-10 from Team A’s 25?
- Is it 1st-and-10 from Team A’s 30?
- Or is it 1st-and-10 from Team A’s 25?
If you said it is 4th-and-5 from Team A’s 30 – you are correct.
Defensive holding is a 10-yard penalty from the previous spot – which was the 20-yard line. Team A now has possession at the 30, needing to get to the 35 for first down.
