The Blues were supposed to be angry following a phantom penalty call against captain David Backes last week in Detroit. They were looking to set the tone for the start of a four-game homestand. The first visitor Tuesday was Nashville, which wasn’t supposed to be able to score at will, coming into the night averaging an NHL-low 1.5 goals per game. Moreover, the Predators hadn’t scored at Scottrade Center in over 180 minutes — the equivalent of three games. If those weren’t sufficient enough reasons for the Blues to pad their 6-2 start, there also was the fact that Nashville was wrapping up a grueling, seven-game road trip. But in a season when the Blues are promoting “Long live the Note,” highlighting franchise performances of yesteryear, the film from the team’s 6-1 loss to Nashville will be gone before fans finish their first cup of coffee this morning. Following Friday’s loss at “The Joe,” the Blues showed only spurts of having caffeine in their system, falling at home for the first time this season in front of 15,206 and also for the first time in back-to-back games. Listening to Blues coach Ken Hitchcock tell it afterward, however, Tuesday’s result wasn’t unfounded after all. “This is a team loss that has been coming for a little while,” he said. “We’re not competing at the level we need to compete at. We’re allowing the other teams’ competitiveness to frustrate us, and it pushes us into individual hockey rather than team hockey. And that’s the thing we have to address. “We have to become a team again, reform ourselves into a team that loves to play in these type of hard games. We looked like we were discouraged by the level out there.” Nashville led 5-0 before the Blues woke up in the second period, outshooting the Predators 14-3 and scoring their lone goal of the game — a power-play goal by Alex Pietrangelo.
