This is the ultimate dick move by the ultimate dick player.
He sleeps fine.
He is doing exactly what he is paid to do, and what the team wants him to do: Mix things, up, and get under your skin.....get you focused on him and off of your game.
He's just another in a long, long line of infamous NHL antagonistic/dirty players. Sean Avery, Theo Fleury, Brad Marchand, Nazum Kadri, Andre Shaw....on and on from past to present.
Some "dirtier" or more notorious than others.
If he gets under your skin as a fan, then you know he is doing his job VERY well.
Whether or not you agree with his (or others) actions is a whole other matter.
Point being: It's been a part of the game since nearly the inception, and it's still here today.
