His arm was at hip height, how would he hit him with his elbow?
He left his feet for no reason, raised both arms up, and hit Duclair in the head with both. Maybe, MAYBE he is trying to get his arm over the top of his head to clear his stick but all he did was make the contact 100x worse than it would have been. I doubt he wanted to close line him, but there is 0 reason to jump, or raise your arm like that. He took what should have been a mediocre hit, and turned it into a dangerous hit to the head.
