From the article:
"Todd Berry, the executive director of the American Football Coaches Association, said Wednesday that the FBS coaches in their annual meeting unanimously supported a model that would assign Targeting 1 or Targeting 2 to a player who makes forcible contact with the crown of his helmet. Targeting 1 fouls would result in a 15-yard penalty but no ejection or suspension. Targeting 2 fouls would result in an automatic ejection and potential suspension."
One thing that I like about the current rule is that there is no attempt to gauge intent. IMO attempting to gauge intent leaves to much gray area for the refs to inject their opinion. Additionally, the current rule issues punishment based on the result, not the intent. It doesn't matter if a player intended to hit the head/neck area of another player or not, the impact and thus the risk of injury occurred. If the goal is to eliminate contact to the head/neck area, then accidental contact needs to be eliminated as well as intentional contact.
IMO, the only way to really eliminate contact to the head/neck area is to punish all contact equally (I'm not saying that punishment is consistent today, but it has gotten more consistent over the years). Eventually players will adjust attack angles and tackling technique and the risk of contact will be reduced/eliminated.
