I don't know where you're getting this from. Hockey very rarely has fatalities. The only direct on-ice fatality in the NHL's hundred year plus history was Bill Masterton, who died in 1968. Adam Johnson became one of the only players in any hockey league ever to have been killed via on-ice injury.
Anyway, speaking of history, and of the 1960s, San Jose just became the first NHL club since that decade to give up ten goals in back-to-back games. The Washington Capitals better watch out, their worst season ever record might be in danger.
