What loyalty did he owe you? Did you draft and develop the player? Took care of his aging grandparents while he left for the new country? You did nothing. You traded for an asset. He owed loyalty to Chicago. Which he showed by signing a very team-friendly deal. He owed loyalty to Patrick Kane, who obviously helped him a lot. He showed that in spades as well.
I'm an Oiler fan, he doesnt owe me anything. He doesnt owe the columbus fans anything either, as he clearly showed by exercising his right to go somewhere else.
What you dont seem to understand is that the columbus fans don't owe him anything either, it's a two way street. You think that just because the player is justified in moving on, that the fans should get over it and dont have a right to boo. This thread comes across as entitlement - panarin is allowed to leave and you have to be nice to him.
Not sure what all this you stuff is about. I'm not a GM. If that's your stance, then fans have absolutely no right to do anything because they dont have managerial stake in the NHL. By your logic, those fans booing shouldnt bother you, you have no right to complaina but it, he didnt take care of your grandparents. He didnt leave your team in free agency. You weren't in the arena when he came back... etc, etc... weak argument all around. The team drafts players, not us. So none of us have a right to complain when a player we draft leaves?
