Since we're talking about pet peeves of rules...
Ban duplicate numbers. From 1 to 99 there are enough numbers to more than outfit a team. If some school has "retired numbers," well then so sorry, so sad, dress fewer than 99 players. Back in the day many of us played on offense, defense, and special teams, all in the same game! Heck, dressing 90+ players, most games 50 of 'em won't even see the field.
