Been officiating high in Mass for 27 years never heard of a lawsuits. And as far as modifications, MIAA has made them to the NCAA rules (5 time outs, touchbacks placed at the 20, kickoff from the 40, overtime ball placed at the 10 just to name a few) Some leagues play 10 minute quarters other play 11. I’m sure head coaches opinions were never sought. My board services many youth leagues, AYF and Pop and we been using NFHS rules for years. We hold separate rules review. Just don’t blow and throw when the D line jumps and gets back on Friday night.
