On Friday, Laviolette reiterated what he said after the Edmonton defeat.
"Last night's game is unacceptable," he said. "You play enough unacceptable games, and you'll find yourself in a battle you don't want to be in."
The Flyers, who play in Calgary on Saturday night, have surrendered four power-play goals in five attempts over the last two games.
"I think it just comes down to [the fact] we're getting the opportunities to clear pucks and block shots, and we're not doing it - and it's really been killing us," defenseman Matt Carle said, adding that the Flyers need to be more aggressive and not sit back as much on the penalty kill.
Edmonton took a 1-0 lead Thursday on Taylor Hall's second-period, power-play goal.
"It seems like we're always playing from behind," Carle said. "I can't remember the last time we scored the first goal in a game, and that's been the biggest thing that's killed us. It's one of the things we need to iron out as we come down the stretch."
In Thursday's second period, Edmonton outscored the Flyers, 2-0, and outshot them, 15-6.
"I don't understand how we can come out flat like that in the second period," said center Claude Giroux, who has 15 shots over the last two games. "I mean, it's big points. We know that."
After having been near or at the top of the Eastern Conference in the first three months, the Flyers have just a 7-8-3 record in the last six weeks.
"Maybe we just got too comfortable," Giroux said. "We're a team that works hard; we're relentless on everything, and we haven't played a full 60 minutes in a long time. . . . We need to be better at starts of games and need to have a better start in Calgary."
Laviolette said the Flyers "need to move north, and not waddle east to west."
As for the penalty kill, Laviolette didn't sound overly concerned.
