There's a small but crucial semantic difference between what you and I are saying (unless I am misunderstanding you, in which case my bad).
You seem to be saying that if Schenn hit Krejci, and initially made contact with the chest before then making contact with the head, it would be legal...as long as the primary point of contact was not the head.
I believe the rules say that if Schenn hit Krejci, and initially made contact with the head before then making contact with his chest, it would be legal...as long as the primary point of contact was not the head.
Schenn 100% makes contact with Krejci's head, that's not up for debate. The question really then becomes, was the head the primary point of contact or did Schenn get enough of Krejci's body for it not to be?
Clearly we each have our own biases here. I think it's hard to tell from the angle, you think it's a slam dunk no brainer. We'll have to wait and see what the DoPS thinks.
