I can see this getting 1 game arguably. It was an NHL hit that ended badly, and they decided that it was a hit that shouldn't have been thrown. Not sure I agree with the basis for making decisions there, but I can understand it. 3-6 seems severe to me, however. Reputation's probably part of that, the injury is... unfortunately it seems like one of those things you just have to take if you're Torres because he's earned his rep over the vast majority of his career.
But anyone who thinks Torres was headhunting should know that the 2 are best friends off the ice. No way he was trying to decapitate him.
