At the time, Chris Kunitz's shift as a penalty killer several minutes into the third period Sunday seemed like it might be the story of the Penguins' game against the New York Rangers.

After Penguins winger Matt Cooke left his team short-handed for five minutes for elbowing New York's Ryan McDonagh with the score tied, 1-1, Kunitz was a madman in the neutral zone.

He pursued. He pressured. He skated furiously. Eventually, he took the puck from New York's Mats Zuccarello, carried it across the blue line and into the right circle, and launched a shot that ticked off of defenseman Dan Girardi and knuckled past the right shoulder of goaltender Henrik Lundqvist at 6:26 for the Penguins' first and only lead, 2-1.

"I thought the momentum was going to help us out. We needed to get some emotion," Kunitz said later, after the Rangers made the most of what became an extended power play en route to a 5-2 New York victory at Consol Energy Center.
