There’s some real, comments in here. LOL.
I have no horses in this race, so I think I can be pretty objective.
Necas looks like he’s near 45 degrees when he sees Trouba, the only thing he can do to protect himself is duck. He can’t brace himself, and it’s fairly obvious his head is the target, probably to him as well at that point.
Trouba literally leaves his feet and extends his left elbow towards Necas head, he doesn’t put it up to protect himself from the boards, because it actually starts to come down when he realizes he’s gonna hit them, and he actually hits the boards with his left glove, head, and other shoulder.
There’s no real contact here, other than the knee dropping on Necas, which I don’t know if there’s a NHL rule for knee drops? LOL.
So, there’s no penalty, no fine, no suspension.
But we all know he was trying to elbow the guy in a vulnerable position with a leaving his feet hit, let’s not pretend otherwise.
The scariest part is the skate blade, no reason for a skate blade to get that close to the back of someone’s head, especially after what just happened. Get mandatory neck guards and teach players not to be so damn stupid about other player’s safety.
