It us absolutely a better idea/plan to spend momey on school security - for kids and personnel, for sure. And games to midnight!?!? That is getting late (and within the realm depending on the methodology employed if instant replay did become a reality for PA’s schoolboy ball); however, and were it solely up to me, I would not, in the first instance, reject it out-of-hand.
As it is, and considering that the hard working, honest, community minded and noble souls that ref scholastic football are often early in the learning curve, mistakes can be made.
So in my humble opinion, if not already evident, a fair and appropriately designed system that would help insure an error by the “judiciary” doesn’t decide the outcome of a grid battle isn’t a bad thought. Why? Well, during my personal labors in the trenches of my profession (of the last 35 years) more than once the ability to go up the ladder of the process (for a review a decision) resulted in a “bad call” being reversed.
Now how it’s implemented is up to the “big brains” (thank goodness) but as long as what that system is doesn’t becime an unmanageable sideshow that unnecessarily (and materially) affects the game - or it’s riunning time - I believe I would be OK (and maybe that’s not possible but I’d still vote to try it out, see the results and then decide).
