With a chance to hold first place in the MassMutual East Division and a chance to clinch a playoff berth for the 15th consecutive, the Pittsburgh Penguins left dejected and unhappy with their performance in a 3-1 loss at PPG Paints Arena on Tuesday.
The Penguins had differing opinions on the exact nature of their foibles, but the undeniable fact was they lacked the same edge they had on Sunday in a 1-0 win.
Teddy Blueger had an opinion about their energy level. Bryan Rust rattled off a litany of shortcomings and obviously had a sour taste.
Mike Matheson was kicking himself for the first goal and for not getting shots through. And he kept going, too.
The loss underscored what the Pittsburgh Penguins should fear if they face the Boston Bruins in Round One.
