If you retaliate, you're the one who always gets the punishment. Either fines, suspensions, or both.
In hockey, if you do this kind of crap someone tries to fight you. And you still get the fines/suspensions/both. Also, seeing the teams more often means i can get some revenge later. We won't see sherman anytime soon, so he can get away with it. And by the time we do see him again, we'll be a different team.
I think the goal was to beat them on the scoreboard, by NOT getting stupid retaliation penalties. And we almost did all things considered.
