You guys as usual are focused on a pointless debate over punishment, intent etc. rather than solving the problem that led to the injury.
Since the configuration of the rink cannot be changed, all the NHL has to do is paint a zone on the ice near the benches and designate it as a "no check zone." If you had such a zone painted on the ice, Chara can't touch Pacioretty until he clears the zone. Otherwise you impose a penalty if an offensive player is checked in that zone. And as far as the concern that the offensive player will camp out in the zone and then get a pass he can breakaway on, you institute a "3 second rule" just like basketball has to prevent taller players from camping out in the lane. If the NHL did this, then this type of injury that Pacioretty sustained would never happen again.
You're kidding, right? Do you think a player moving at top speed would stop just because there's a painted zone on the ice? This is HOCKEY, not basketball. There is no out of bounds on a hockey rink. Hockey at it's slowest is still much faster than basketball at it's fastest. Hockey at full speed makes basketball look like slow motion. Would there be some kind of force field to prevent someone from hitting a player in the zone? No, of course not. The hit would proceed as usual and maybe there would be a penalty on the play. It wouldn't change a damn thing.
MG, you're probably right. Even if Campbell had been the one to make the decision it probably wouldn't have been any different. He still doesn't deserve to hold his position as long as there is the slightest appearance of the possibility of conflict of interest.
JH you're right, too. Nothing will change until someone does die on the ice. And then it'll be too late.
Now Bettman says that Air Canada can cancel their sponsorship if they want because he can easily replace them. Right. Good luck with that.
