Me personally? I'm not sure where I stand in the discussion about essentially removing north-south hits for the purpose of reducing head trauma in hockey. On the one hand, I'm in favor of removing fighting for that reason. On the other hand, I think hitting in hockey, both for the purpose of dislodging the player from the puck, and for the reason of wearing your opponents down, has always been much more central to the game than fighting ever was.
Again, I don't like the NFL comparison, because the objective of hits are very different. Also, many of the hits that they removed in the NFL by putting more onus on the hitting players were already egregious acts of violence that wasn't allowed in hockey.
Fair enough then, cant much argue with playing it safe. I too tend to do the same in most conversations.
I could be completely wrong but I do feel there are ways to hit a player with their head down; as well as having the head down is a disadvantage to the offensive player, in the first place
Even if contact is avoided on most players with their head down.. that doesnt mean a free zone entry or successful play is made
Personally, I feel the 'keep your head up' comments are, almost always, inadvertent ways of not wanting to remove big and powerful body checks. Which I dont want to either.. but as for player safety, I think the rules need to change to reflect this.
And if the rules do change, the players will adapt. They are much, much better at doing so than 99% of us can understand or will ever give them credit for. They know their bodies far more than we ever will
