There was an outcry when football banned the flying wedge when it was deemed too dangerous for the players. Football survived... The crackdown to hits to the head needs to be much more serious. Even hits like Ference on Halpern should have no business in hockey. Hockey will also survive.
It wouldn't just survive, it would be better.
What ference did to halpern was disgusting. To me, there is no other solution than demanding the firing of Campbell and Bettman. As simple as that.
