Ok so since I have this obsession with playing devils advocate:
Players are allowed to literally punch people in the head, crush them into the boards, shoot frozen solid rubber pucks at your face, accidentally high stick your eye out, stick you in the nuts, slash your finger off, tell the other player that they literally **** every single person in your family, etc etc etc
But taunting players by licking their nose is completely over the top?
And this comes from someone who absolutely despises Marchand btw. I get it, it is gross. That mouth and tongue has probably been rummaging through garbage before the game but some people make it sound like Callahan was raped and violated.
Suspension is too harsh IMO. Licking another player needs to be something the players police themselves on. I wish Callahan would of gave a full effort punch straight to the face of Marchand instead of nothing really because he was afraid of getting a penalty, and then the refs just put the whistle away for this one time.
Marchand gets his lick. Callahan gets his retribution. Refs don't give any guy a penalty. That will really teach Marchand that licking isn't cool because there will be no benefit to doing it. Except for a punch to the face that surely won't feel nice.
