What are the specifics? Is grabbing the jersey at the neck the same as grabbing the shoulder pads?
Hair is not protected by rule. Fair game for a tackle.And if they have a pony tail hanging out from behind their helmet, is that a legal means of tackling?
You are the football official and I am not, however I'm questioning your application of the rule here. The rule is in place for the safety of the players. If you only call it when someone is in a position to get hurt aren't allowing the play to sometimes happen? Doesn't this lead to inconsistencies? Defender from Team A can grab a nameplate, pull to the side, and be flagged. Defender from Team B can do the exact same thing, but because the runner's legs don't fold the same way it's not a penalty?I know the rules very well, but in most cases when I'm deciding on a foul I look for indicators. For a horse cllar tackle, the indicator is whether the legs are folded back or under the player. The purpose of the rule is to protect the legs from those exact situations. The rule started in the NFL when Terrell Owens had a leg broken by being pulled down backward. A couple later it was added to NCAA, then it made its way to high school a few years ago.
If the runner is pulled backward, the legs tell the story. If they are pulled to the side and back in a way that puts the legs at risk, it's a foul for horse collar. If the player sins or falls to the side such that the legs are not folded, it's not a foul.
FWIW, my indicators to call holding are also the legs and feet. I hear coaches yell to their blockers "Keep your hands inside" and I think "Makes no difference, I'm not looking at the hands."
