I work games in Oregon ("the experimental state") and this is NOT a non-federation rule being implemented.
From the 2015 NFHS Football Rules Book under "Comments on the 2015 Rules Changes":
- EXCESSIVE CONTACT ADDED TO UNNECESSARY ROUGHNESS (9-4-3G): With an emphasis on risk minimization, the unnecessary roughness provisions were expanded. No player or nonplayer shall make any other contact with an opponent, including a defenseless player, which is deemed unnecessary or excessive and which incited roughness.
Brad Garrett's interpretations of what is unnecessary and excessive (which the originally posted video was part of) can be debated. However, it is a rule in all states that use NFHS rules.
And by interpretation in my state, the rule changed nothing from last year. If it was a foul last year, it's a foul this year. If it wasn't a foul last year, then it's not one this year either.
Ralph can chime in, but the report I got from the January meeting was that there was great debate on how to proceed on the issue of safety, while retaining the "integrity" of the game. The rule passed was intentionally vague, as to allow states to interpret the way they felt it should apply, and to find some wording that would get a rule passed. That's vagueness is great for states that have a strong training program. For those that don't, it moves the interpretation from the state level to that of each individual official, and that is NOT a good thing.
