There are certain parts of the Blackhawks’ game that rarely change. Yes, that includes that much-maligned power play; it’s usually not so good. Their penalty kill is usually on the opposite side of that spectrum: reliable, strong and stingy.

Last year, however…

“That beginning was atrocious,” coach Joel Quenneville said.

Yeah, it was bad. More like horrific (we’ll show the numbers soon enough). And with some of the losses the Blackhawks took this offseason, one figured it would be rough again this season. Instead, it’s back to its efficient self.

The Blackhawks’ penalty kill has rebounded this early season, allowing nine goals on 59 attempts and sitting sixth overall in the NHL (84.7 percent) through the first 15 games. It’s a bit surprising considering the Blackhawks no longer have PK stalwarts such as Niklas Hjalmarsson, Marcus Kruger and Marian Hossa. So why was it able to find success again this fall?

“Well I can’t tell you all of our secrets,” said Tommy Wingels, who’s been part of the Blackhawks’ PK this season. “I think a summer off and giving the team and a unit a chance to reset is important. I think Ulfie’s [assistant coach Ulf Samuelsson] come in here and brought some new ideas. First and foremost, goaltending has done a good job. No matter if you’re the best or worst penalty kill, your goalie has to be your best player, and so far we’ve been fortunate to have that.”
