In a season full of spectacular performances, Nathan MacKinnon may have authored his masterpiece Tuesday night. It wasn’t just that MacKinnon had at least four points for the eighth time this season, including seven times at Ball Arena. Or his third hat trick of the year. Or that he reached 50 goals for the first time in his career, or pulled within two points of the franchise record set 42 years ago. It was how he dismantled the Minnesota Wild, a team that needed to avoid losing in regulation to keep its playoff chances.
