I had only seen the replays as the end-of-game summary on TV when I made my last comment. Seeing the outcome and more review of it, it is a bit much from Wilson. Aggressive contact is one thing, but it needs to be a bit more controlled. You can lay people out (Byfuglien has been doing it all playoffs) without the injury/head contact.
For sure, I'm all for good, clean, aggressive hits, but the NHL really needs to start cracking down and anytime there is head contact fine or suspend accordingly. Guys will adjust and start taking the body and not the head.
My concern has always been (and this goes for the NFL too) the responsibilities of the hit-ee. Clearly this isn't the case with Wilson/Aston-Reese last night, but if it is movement by the hit-ee at the last split second that creates the head-shot, why is the hitter held responsible for what would have otherwise been (in all likelihood) a clean hit?
To me it comes down to whether a player maintains what they were doing, or actively makes the hit worse on themselves. In this case Reese did clearly see the hit coming a moment before it did, but didn't have time to do anything except maybe brace himself a little bit. Certainly lifting up a bit would have protected his head, but on this case that onus is not on him. On the other hand had he been standing tall and lowered himself right as he saw the hit coming, then yes, I believe he would be partially to blame for the outcome.
I watched this hit a bunch of times, and found a new opinion with every angle. I truly to not believe Wilson targeted the head. I think he wanted to deliver a devastating hit, but I think he meant for it to be shoulder to shoulder. That said, the contact was made, there was an element of charging there as Carcillo pointed out, and I think a suspension of 1-3 games is justified, especially since their was no penalty in the game.
