Below is this week's segment - Misunderstood Rules: 3 Seconds - Listen
It’s hard to go to a basketball game and not sit near other fans who are yelling about the officials not calling three seconds. The 3-second rule is one of the most misunderstood rules in the game of basketball.
The purpose and philosophy of the rule is to not allow a player who is significantly taller than his or her opponent to camp out in the middle of the lane and create an unfair advantage. The 3-second count is in effect whenever an offensive player has at least one foot in the lane when his or her team is in possession of the ball. That count stops as soon as a try – a shot – is attempted or a try is imminent; and the count cannot start again until there is control of a rebound.
Keep this in mind at the next game you attend.

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.
