I've only just watched the video explaining Engo's suspension and it is complete BS. They say that Abdelkader doesn't significantly alter his body position when Engo begins to move in for the check, and yet while they are saying this the slow motion replay clearly shows Abdelkader going from a bent over position to a significantly more upright position. If Abdelkader remains bent over, as they say he did, Engo gets him square in the shoulder/upper arm region and knocks him over. But Abdelkader raised his body up and changed Engo's point of attack from his upper arm to his head, through no fault of Engo's.
I get that they upped the suspension because of his history, but the explanation as it stands is ridiculous and not what the video shows.
Meanwhile, they get it completely right with the Wilson/Schenn hit, which showed the same amount of body position change (albeit in a different direction) as this one and they let that go. What gives?
