The third period sequence that included the Penguins killing off four minutes of Matt Cooke penalties followed just nine seconds later by Matt Niskanen's go ahead goal will likely stay in fans' memories for quite some time, and could be one of those moments that help define a season.
The Pens held on for the 2-1 win, their 10th straight and fourth in a row against the Caps.
They're doing it without Evgeni Malkin.
And now without Kris Letang.
They're getting goals from guys not named Crosby, Kunitz or Neal.
And playing sound defense with solid goaltending.
In other words, the rest of the Eastern Conference could be in big trouble.
