Nathan MacKinnon hacks official's leg with his stick in Boston; suspension incoming?

The play occurred off of a faceoff that MacKinnon clearly thought was either done unfairly or that Bruins center Erik Haula had cheated on without a call. Either way, it did not look good. Take a look for yourself.

I can't imagine a scenario in which the League does not nail MacKinnon with a lengthy suspension. After what we just saw with Brad Marchand being issued a 6-gamer for his antics on February 8th involving goalie Tristan Jarry in full protective gear, Mack's hack on the official is likely to earn him 10+ games.

Of course, MacKinnon doesn't have a lengthy suspension history like Marchand, but I don't think there's any question that you cannot do that to an official.
