It’s often been said that the most difficult call to make in all of sports officiating is the block/charge in basketball.
When you’re watching your next basketball game, the key for the official in getting the play correct is determining whether or not the defender gets in a legal guarding position. Many times we’ll hear announcers and commentators talk about the defender having his feet planted and stationary; that actually isn’t required by the rule. The rules require the defender to be in a legal guarding position, which is a position where it’s facing the offensive player and they’ve established a position in advance of the offensive player.
If the defender is in illegal position, the contact is now a charge.

Be the Referee: Illegal Substitution/Participation

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.
