Why haven't they come out and said as much. They're not giving any sort of definition as the aforementioned rule suggests.It was already against the rules but the fine was so slight that it did not deter anyone from doing it. All the NFL has done is stiffen the fine to make what is already illegal more detrimental.
If players know they can't hit a certain part of the body, fine. Don't tell them they can't hit the opponent as hard as they can in other areas though.
