Below is this week's segment - 40-Second Play Clock - Listen

One of the rules changes in high school football this year involves timing between downs.

All varsity games will be played with a 40-second play clock that begins after the conclusion of the previous play, with exceptions for things like timeouts, penalties, measurements and at the start of a period – when a 25-second count will be used.

In experiments in Michigan over the past few seasons, the 40-second play clock proved to improve the pace of play and consistency between plays because it is not dependent on the referee’s subjective signal. And while some schools may choose to purchase visible play clocks for their fields, it is not required. The Back Judge, who has the primary responsibility for the play clock, will signal at 10 seconds and count the last five seconds.
