Agreed! This was never the intended use of the rule. The rule was intended for someone intentionally using their helmet to inflict harm in the open field (think crossing routes and blind side blows) You know “targeting” an opponent with your helmet. They wanted to protect defenseless players.
If they want to flag defenders they need to extend the rule to be able to flag runners that use their helmet in the same manner.
Disagree. It was also intended to stop leading with the crown of the helmet, essentially spearing. Powell was close, but I don't think that qualified. Millen it was 3 inches of helmet from being a clearly legal hit. So borderline at worst.
