'Shame on us': Cooper irked Lightning took costly penalty in 3rd vs. Bruins

The Tampa Bay Lightning may have taken only one penalty during Tuesday's 3-1 loss to the Boston Bruins, but head coach Jon Cooper still had harsh words for his squad.

"It's a tie game in the third period, and you come in here, and you want to take penalties against Boston and can't kill off one penalty? Shame on us. Anything else?" Cooper told reporters postgame, according to Bally Sports Florida.

The Lightning and Bruins were knotted up 1-1 entering the final frame when Bolts rookie defenseman Nick Perbix took a tripping penalty on David Pastrnak just over one minute into the period.

Bruins winger Taylor Hall potted his second goal of the game on the ensuing power play, and his tally stood as the eventual game-winner.

Cooper was frustrated that his team didn't come out firing for the final 20 minutes after a strong second period in which Steven Stamkos potted his 999th NHL point with a one-timer on the man advantage.

"We played well, we had them on their heels, and it got us back in the game," Cooper said. "We deserved to win that period, and we did, but that's not where the game ended."

The bench boss added, "We just didn't have that push we had in the second. Maybe we needed to get the lead in the second. We didn't. But again, winnable game, tied going into the third, and we just didn't kill off the penalty we needed to."

Brad Marchand iced the contest with an empty-netter. Tampa Bay outshot Boston 28-26 during the defeat.

Tuesday marked the Bruins' 13th straight victory at home to start the season, building on the NHL record they set with last week's win over the Carolina Hurricanes.

The loss dropped the Lightning to 13-8-1 on the campaign.
