I would hate it. I don't cheer for assholes. That's also why I don't really like Kassian, because of his history with breaking Gagner's jaw.
I think a borderline example would be Marchand, at least Marchand's antics are mostly harmless and not meant to break someone's neck on purpose.
Matthew Tkachuk I would absolutely hate if he were on this team. Slew foots Davidson first game in the NHL pretty much told me all I had to know about him. He could score 100 points next to McDavid and I would still hate him.
Oh yeah and Brandon Manning, good lord was it hard to watch him. f***ing hell when he scored on a McDavid assist, McDavid didn't even want to celebrate with him lmao. Having him on this team was like torture.
And I also didn't really like Lucic when he jumped that one guy, but Lucic was pretty tame here and looked disinterested so w/e.
