Below is this week's segment - Primary Areas - Listen

In just about every single basketball game ever played, there are times where fans will turn to each other and wonder, “Why did that official make the call when there was another member of the crew that was a whole lot closer to the play?”

The most important thing in all of officiating and especially basketball officiating is angle is the most important element for an official.

There will be many times during the game that the official that is closest to the play actually has the worst look or the worst angle. Many times the player is going up in the lane for that shot, and the whistle will come from one of the two outside officials because they had the perfect angle to see all the elements of the play and can rule correctly.

Be the Referee: Illegal Substitution/Participation

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 – Illegal Substitution/Participation - Listen

We’re on the football field this week with 23 players.

Twenty-three is one too many; there should only be 22 on the field at once – 11 on offense, 11 on defense.

But on this play, the offense had a 12th player lined up on the field.

What’s the call?

It depends on when the penalty is spotted.

If the officials catch it before the play is run, that’s an illegal substitution and a 5-yard penalty.

But if the ball is snapped and a play is run with 12 on the field – and the 12th player is not attempting to get off the field – then it’s illegal participation and a 15-yard penalty. It’s also a 15-yard penalty if the offense uses a substitution to create a deception.
