If you look up in the dictionary besides Classless, this hit by Andrew Shaw might appear.
The Habs forward was just coming back from a concussion that kept him out for a whole month. Maybe that wasn't long enough for Shaw as he delivered a blindside hit on Jesper Fast who wasn't even in control of the puck.
The Montreal Canadiens' 3rd liner was given a 5-minute major for interference and a game misconduct on the play. He also dropped the gloves with J.T Miller who clearly didn't want any part of it but stepped up for his teammate nevertheless. Counting his 2-minute minor for interference on Ryan McDonagh earlier, that adds up to 22 penalty minutes in less than 5 minutes of icetime for Shaw, what a night.
