I think it was a good no call. Wasn’t 9-1-3 since I don’t think he led with the crown - I think he drove through his shoulder, and helmet contact was after that.
Just because initial contact may be with a shoulder, that does not relieve the attacker of responsibility to avoid targeting contact to the head-neck area of a defenseless player. The indicator is there - he lead with his head. The contact was forcible. And the receiver was still defenseless. This was targeting.
By contrast, I saw a play in a C-USA game a couple days ago in which the defender made forcible contact to the head of a receiver just after he caught the ball, but the defender was simply running straight ahead, vertically upright, and just ran through the receiver. There was no indicator, at all. No foul, and, correctly, no call.
