As long as players want fighting to stay it's not going anywhere... a couple people have mentioned the documentary "Ice Guardians" and I want to +1 that, it shows how important fighting really is for the star players in ways that we as fans can never see..
Another one is, "Untold: Crime & Penalties" on Netflix.. for the people who say fighting is the reason hockey isn't popular in the States.. that doc is about a junior team built by some kid, it was a team full of goons whose M.O. was to just kill the opponent.. they were selling out by like the second game lol.. safe to say a vast majority of people enjoy it, only a vocal uninformed minority want it gone..
I don't mind trying to find ways to make it a bit safer, like no take downs or something, but banning it entirely would be bad for the NHL in it's current state.. like others have said, until every rule is enforced 100% and no one is taking any cheap shots fighting needs to stay, and I bet damn near every player would agree with that
