Right. As I've said multiple times, including in the post you quoted, it is a legal hit as far as the NHL is concerned. It being legal is different than it being a good hit.
Agreed. Sometimes head contact isn't avoidable. But the approach he took, by crouching and then launching upwards, ensured far more impact went to the head than if he had leaned into the hit.
Now, as I've said multiple times, the NHL has determined that if you keep your feet touching the ice, even if only by a millimeter, at the point of contact, then you're free to launch upwards as hard as you want. I think that's a deeply stupid approach, but it's the one the league has taken.
