The linesman made a bad call. It should have been icing. That being said, that was way too close to the net for Swayman to not play it with :20 left. It would have been an easy play to McAvoy in the corner. Also, Forbort has to play the puck cleanly there. Play to the whistle and don’t assume the icing. They know how bad the officiating is in this league, they shouldn’t assume that the right call is going to happen all the time.
