Exactly right. Making the penalty more severe never results in the intended effect. HS officials are already awful by and large of flagging UNS - changing it to a live ball foul would just make it worse.
Same reason why too many basketball officials are scared to call a technical foul. Two shots and possession is "too severe" and it deters officials from penalizing unsporting behavior.
Part of our job is to understand the difference between , what
we SEE as being UNS conduct & Personal Foul is a "Bright red line", but when that line is crossed -
IT'S CROSSED. NFHS; 2.16.C (Flagrant) helps describe that "red line" and ignoring that line can, and usually does, create far more problems.
