Below is this week's segment - Basketball Instant Replay - Listen

When watching a college or NBA game, the last 2 minutes of the game can seem like they take forever, especially in recent years where more and more judgment calls made by officials are subject to instant replay.

At the high school level, video is not used to make a ruling or confirm or overturn a call made during the course of the contest. The only time video review is used at the high school level is at the MHSAA Semifinal and Final games held at the Breslin Center. In these games, video review can be used only to determine if a shot was released in time at the end of the 4th quarter or overtime or if that shot in those periods was a 2-point or 3-point field goal when the shot is released near the 3-point line.

The MHSAA believes that this very limited use of replay in these games at the very end of the tournament series in boys and girls basketball is the right call.

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.
