He didn't want to hurt him. Why would you look at the puck when you're lining someone up for a hit? He hurt him because he wasn't prepared to take the hit at all because he wasn't paying attention to what was coming his way right in front of him and he fell awkardly into the boards because at the last possible moment he tried to get out of the way, which is the reason Janssen got his head instead of the shoulder.
He didn't wait for him to get near the boards, either. That's just where he happened to be when Janssen got to him.
its the fact that we was looking at him for a long time, and kinda waited till he got closer to the boards to hit him
it was obviously late, and he was going for the head, so i think he hit him, but thats my opinion, you got your right to yours
