Chicago has allowed only four power-play goals in 63 chances in the playoffs. It's a good thing because of its problems on its own man advantage. The Blackhawks have killed off four of five power plays against the Bruins in the Stanley Cup Final. Coach Joel Quenneville credits his players, pointing out the work of Michael Frolik and Marcus Kruger. "I just think that duo is the thing that's been the most noticeable," Quenneville said. And Kruger and Frolik credit their ability to "read off" each other in order to know where to be.
