The Pittsburgh Penguins weren’t expecting any surprises Friday night when they rolled into Edmonton.

The Oilers, however, had other ideas, jamming a shocker down their beaks at a delirious and jam-packed Rexall Place.

In a game between the first-place team in the East and the last-place team in the West, nothing unfolded the way it was supposed to.

Not with Ryan Nugent-Hopkins scoring early in overtime to stun the Penguins, and a big chunk of the entire hockey world, with the monumental 4-3 upset.

“Run and gun is not exactly how we want to play every night, because you can get caught that way, but when we match skill against skill we do pretty good,” said Nugent-Hopkins, who finished the night with two goals and an assist in almost 22 minutes of ice time.

“It’s a big win against a really good team in the league. Just to show that we can do this gives us some more confidence.”

With many in the sold-out house expecting a blowout, what they got instead was a fast and exciting display of hockey the way it was meant to be played, with speed, creativity and flair, and the Oilers matching Sidney Crosby, Evgeni Malkin and the Penguins stride for stride.
