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 – On the Line - Listen

I’m on the line today … but am I in or out?

Have you ever stopped to think about how the boundary lines of a field or court mean different things in different sports?

In basketball for example, if the ball touches the baseline or sideline, it’s out of bounds. Same if a player is in possession of the ball and touches the line.

Football is the same. A player is out of bounds if that player has the ball and touches the sideline.

But in soccer? The ball is still in play until it completely passes the line. If the ball is sitting on the line, it’s still in play.

A tennis ball on the line? That’s in and a great shot.

Volleyball? Also in.

And then you have baseball and softball – where a batted ball that hits the foul line … is fair.

Know the lines and you’ll always know if you are in … or out.

Be the Referee: Basketball Over the Back

By Sam Davis
MHSAA Director of Officials

January 13, 2026

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 – Basketball Over the Back - Listen

Did you know there is no such thing as “over the back” in basketball? If two players are going for a rebound and the player behind another player is able to grab it over the top of the player in front – that’s not necessarily a foul. He or she did not go over the back.

The player behind another player may have committed a foul such as bumping the player in front, or pushing that player – gaining an advantage to grab the rebound – but that would be whistled for a push or grab. Not over the back.

A taller player or player who can jump higher grabbing a rebound is not a foul. It’s only a foul if they create an advantage by pushing, bumping, or any other kind of illegal contact while in the process of going for a rebound. Fans yell over the back all the time, but an official will never call a foul for going over the back.
