Sorry, but I disagree. As soon as the Sedin sisters turtled, the other guys would just start looking for someone else who was willing. I've never seen NHL guys off a face off to start a game beat up a person who clearly was not willing to engage in the fight.
(well except for that KHL game a couple years ago, the team that signed a bunch of AHL goons)
I don't think I need to post the YT of Emery pummeling Holtby who wanted nothing to do with it. Guys who are there to fight, or are looking for a reason to keep up in the NHL, are going to do just that. Hendricks said that during the 24/7 with Washington about why he always has been a fighter in his career.
