As a school board member, administrator, coach or other person "in charge," I'm guessing the toughest problem here is being on the line. This year, I'm at 96, Two years from now, I'm 113, Four years, 102, The last thing I want to do is flip back and forth from 6 to 11 man, and since I can control the 11 to 6 man switch (it's our choice to play 11 vs 6, but I can't choose to stay 6 if the numbers are too high and still play for a district), I'd probably lean to staying crowded field football as long as I can put a team on the field.
Although 6 man football is a great game, I can see where small communities can feel a loss having to make the change. Perhaps the bank in town has already closed, the grocery store has been replaced by a convenience store, or if we're lucky, a Dollar General. A couple more of the storefronts on main street are empty, and this seems like the next kick in the rear. When it's time for those towns to make the switch, they'll know.
