After allowing three unlucky goals, two off deflections and one off a tip-in in the crease, the Capitals pummeled Pittsburgh with 21 shots on goal in the third period, scoring twice and nearly converting on a myriad of scoring chances in the final minutes. After the Capitals mustered just 10 shots through the first 40 minutes of Game Two, Nicklas Backstrom was angry with how his team played. But speaking after Monday’s loss, which put the Capitals down 2-1 in the series, he was far more confident in his team. “We had more shots tonight than we had last game, so that’s a good thing,” Backstrom said after Game Three. “It’s a seven game series and I think it’s so important that you take something positive even if you lose. I thought we played right.” The message was the same throughout the Capitals locker room.
