NFL helmet rule fact sheet is incomplete

0:00 1:23 Getty Images In an effort to further educate anyone/everyone about the new helmet rules, the NFL has published a fact sheet.
You know, the new helmet rule no one ever talks about.
The other new helmet rule appears within the specific forms of unnecessary roughness, prohibiting ramming, spearing, or butting with any portion of the helmet.
The 2018 rulebook removes the terms “violently and unnecessarily,” extending the ban to all ramming, spearing, or butting — with the exception of incidental helmet contact that occurs during conventional blocking or tackling.
The fact sheet doesn’t address this rule at all, providing no guidance of any kind to players and coaches regarding a rule that presumably applies as written, but that will be enforced however the league decides to enforce it, possibly with a standard that shifts and changes from week to week, with no real certainty or predictability as to what the rule really is.
The full scope of the league’s handling of these issues during the 2018 offseason suggests that someone(s) within 345 Park Avenue has become determined to reconfigure the rules to allow the helmet to be removed from the game, in order to fend off the existential threat posed by parents not letting their children play football.
If that’s the objective, that’s fine.
For now, however, no one knows what will happen.
No one knows how the rules will be applied.
So either the NFL has concocted a system of rules that entails no one knowing what the really rules are (which is bad) or the NFL knows that these rules will be broadly and literally enforced and applied, but has decided to conceal that fact (which is worse).
