In games that are no fun to watch, dissecting the corpse is almost unthinkable. Still, here are some of the brutal facts: The Canucks’ fourth line scored three goals, and another tally was put home by Bo Horvat, who used to be a nice person to look at back in 2013-14, when the Stars could say, “Ha! We have Valeri Nichushkin instead!” That looks like it will be the case again next year, but when successes of other players remind you of your own team’s difficulties, they go down even more bitterly than usual. Val is not back yet.
