With no real deterrent players keep doing things to keep them off the ice via the Department Of Player Safety.
Jack Johnson knows better than to hit like that, he had Tlusty's whole side profile he could hit and chose not to.
Johnson gets tagged with 9 games. 1st suspendable offense so it stays under 10 because he didn't max out on a couple of categories. Note we don't care Tlusty was injured on the play, that hit cannot happen in hockey, injury or not.
I have a feeling we are going to see a lot of suspensions this year, but none with a duration that will actually make a player think twice about their on ice actions.
