Forward Johnny Gaudreau has 14 points (three goals, 11 assists) but hasn't scored in 12 games. Center Mikael Backlund has gone seven games without a point and 12 without a goal.
"We still know we have way more to give," Giordano said. "We haven't put together those games where it's just been total domination like last year, but I feel like the speed and moving pucks quick and making plays as a team, a five-man unit is coming, for sure."
When the offense isn't producing, mistakes with details like the Flames made Sunday can be costly, especially against the Capitals, who lead the NHL in averaging 3.94 goals per game and are 8-0-1 in their past nine. Giordano got caught pinching at the left point, leading to a 2-on-1 and Vrana's first goal, which tied it 1-1 at 11:01 of the first period.
The Flames had all five skaters caught up ice on Vrana's go-ahead breakaway goal, which completed his first NHL hat trick. Goalie Cam Talbot allowed two short-side goals, including a backbreaker to Lars Eller from the right circle with Washington on the power play that made it 4-2 at 2:20 of the third period.
"The effort was definitely there," said Talbot, who started for the first time in six games. "I think that after a road trip like this, maybe fatigue sets in a little bit after a hard-fought game again [Saturday] night. But I thought we did a pretty good job of managing the game, and it's just an extra save away from maybe coming back to tie it up."
With a chance to get some much-needed practice time later this week, the Flames said they believe they will be able to clean up some of the areas that have been plaguing them. Although the flight home would have been a happier one with a win Sunday, they said they're confident progress is being made.
"I'd say overall it was a step in the right direction over the trip period," Mangiapane said. "We had a big comeback win there in Nashville and then we carried it over, so I think we've got to keep building off it. A disappointing loss, but I think overall it was a good trip."
