Below is this week's segment – Football Rules Similarities - Listen

Last week we highlighted some major differences between high school football and the college and pros. This week — how about some of the things that are similar?

New as of last year is the addition of a tackle box when judging intentional grounding. In high school, like college and pros, the QB must be outside of the tackle box and throw it past the line of scrimmage for it to NOT be intentional grounding.

Horse collar tackles are penalties at all three levels of play. The ball carrier must be pulled down backward or to one side for there to be a foul … but if there is, it’s 15 yards.

And a receiver at the high school level needs to have a body part down in bounds, the same as in college. But the NFL requires two feet in for a catch.

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.
