So, what you are saying is that players in Texas are more mature, and have greater skill and experience than any other state. After all, they play by these very same NCAA rules, and I dare say that there has been no degradation in maturity, skill, or experience since those rules have been in place. Quite the contrary, in fact. Their skill levels, in particular, are far above where they were only 10 years ago.
Far be it from me to question your Delusions about the maturity, skill set or experience capabilities of regional children aged 12-18 (or so), as you are entitled to your conclusions.
However, my suggestion was a response to a purely safety related issue, that, at best, is a thankfully EXTREEMELY RARE occurrence in the majority of HS level games, regardless of imaginary regional maturity and/or talent assessments.
If/when a player, successfully intending to deceive opponents into believing he was a runner, was initially contacted in such a manner to displace his helmet, and his impetus continued his movement, placing him at additional (unnecessary) risk, from other defensive players who may have also been deceived by the circumstances, (legally) committed to stopping his feigned advance, my inclination would be to prohibit, or limit, additional contact due to the increased vulnerability and exposure to serious harm, from the unfortunate (and rare) loss of head protection.
My, limited experience in such specific situations, suggests the most immediate and successful way to do this would be to "(loudly) blow the play dead", hopefully before any additional contact (legal or illegal) occurred, likely creating a IW situation, which although somewhat inconvenient seems far more practical than risking unnecessary serious injury.
However, as with most EXTREMELY RARE situations, the action chosen would largely depend on the unique actions being observed in this specific situation, and the judgment and ability of the covering official to weigh the specific, and unique risk, to only THIS play being observed, to guide his decision.
