Under NFHS code, unintentional illegal helmet contact is still a foul. Intent's not a factor.
There are 3 distinct types of "Illegal Helmet Contact" under the NFHS code, each of which, as you note, is a separate and distinct foul. What I was referring to are those situations where NONE of those 3 specific fouls occur, but there is contact between the heads of opposing players. Often, such contact is simply the result of two individuals, moving at considerable speed, resulting in contact of their respective heads.
In these situations there may well be no indication of who, is actually guilty of contacting whom, and therefore there is no foul committed by either party. I was suggesting the verbiage that, "If you have
any contact to the head ", is somehow an
automatic penalty, is simply far too broad a comment.
