I see helmet to helmet along with shoulder contact. I'm fine with this flag.
Like you, I also see contact between two helmets. What I do not see is the use of the helmet as the primary application of force in any angle video, at any speed. The defender led with the shoulder, and the helmet-helmet contact is
incidental. I'm sure you can agree that officials can't penalize every contact between helmets. I mean, the helmets came into use as a recognition that head-to-head contact is largely unavoidable, right?
What the spirit of the spearing rules intend, and the recent clarifications on both sides of the border attempt to minimize, are those cases where the helmet-to-helmet contact is the primary and unnecessary delivery of a blow.
