It is likely that he died because of some unreported injury caused when he was playing hockey or that his coach pushed him too far. The most likely thing is that he was murdered for not following the rules that the NHL sets for their players. His family should push for justice.
NHL bears the responsibility for the death of former Avalache winger Marek Svatos. This is because his death was related to the past game experience. If it were not for this, he could have been alive. Therefore they must take the responsibility and do the right thing through compensation of his family.
Yes, the NHL bears responsibility for the death of former Avalanche winger Marek Svatos because it is such a hard-hitting sport. If he had not been knocked down as many times or been injured, he may still be here today. The NHL needs to change its rules to prevent these injuries.
Marek Svatos died of accidental overdose on a medication. His last season in the NHL was in 2011. His overdose does not seem to have any relations to his playing of hockey so I do not see how the NHL should be held responsible for his death. They only owe him a moment of remembrance during a game.
