The NHL was founded on November 26, 1917, almost 10 years before the Chicago Blackhawks came along in the original six. In 102 years of existence, no one has ever played every game of an 82 game season while taking zero penalties.
Granted, players have played a full season before without doing so, however the feat hasn’t been done again since the NHL switched to an 82 game schedule.
Yet through 55 games with the Chicago Blackhawks this year, Dominik Kahun has yet to commit a penalty.
It’s surprising to see a rookie in a situation like this.
