I am totally serious?
If it makes you feel better, Thank you Big John (or whomever, whatever brought "adornments" to the level of a POE). Despite all the complaints about poorly written, subjective rules, the NFHS rulemakers got the adornment prohibition right. Rather than compete with the creativity of American teenagers, and a lot of immature collegiate and professional former teenagers, we have guidance that beyond a "moisture absorbing" wrist band, properly located and a specificly sized white towel, NOTHING ELSE is authorized.
Simple, direct and understandable. There is likely an element that will always search for some previously undiscovered way to call attention to themselves. It will likely never stop, but prevention is relatively simple; is it (whatever "it" might be), a towel, a wristband (or some of the other limited exception)? If the answer is "no" ( which should be considered "no" followed by a period), case closed.
NFHS rules close this door, if collegiate or professional rulemakers want to open it back up, that's up to them as well as "on them".
