So, while some may disagree , it is my intention to follow the recommendations from the NFHS.
NFHS General instructions for Football Line to gain crews
#12 With the 40- or 25-second play clock, it is possible the ball may be snapped prior to the down-marker indicator being set. Should this
rare situation occur, the HEAD LINESMAN shall drop a bean bag at the spot where the DOWN-MARKER INDICATOR OPERATOR shall
spot the down-marker indicator.
We have teams who coach their chain crew to intentionally sloooow dooown when strategically necessary! Just like ball boys on the field, those days ended with the 40 second clock.
For those of you saying you are waiting for the down box, the 40 second clock is running during that interval (unless you are changing that also) if it gets below 25 your need to reset it to 25. This causes more totally unnecessary delays.
Simple put, if you follow the recommendations from the NFHS, you will get quicker chain crews and the game will move along smoother .
If you want to intentionally ignore the recommendations, your play clock is more than likely going to go below 25 a heck of a lot more than those following the recommendation.
That's my two scents
