I was in Vancouver when Marchand punched Sedin in the face about 5 x and it really set the tone. Sedins were passsive but if ever there was a time to stick up for yourself that was it. Sedin had about 6 inches and 30 pounds on Marchand. If he would have belted him or ragdolled him which he could easily have done I believe it would have been a different series.
Larry Robinson was a gentle giant but every once in while when someone took liberties and went too far with him or a teammate he would go batshit crazy. It changes the dynamics if the opposition knows that if they get stupid they will pay. Bullies are gonna bully until you stand up for yourself.
So to your point, yes, I want to see every leaf player fight tooth and nail for themselves and each other. Get scrappy, don't take shit from anyone, ever. For all of Kadri's bad habits, he has that intangible. We seem to be going in the exact opposite philosophical direction.
