A listless start.

And two wasted power-play chances in the third period in which the best the Flyers could muster was one puny shot.

Twice now, the Flyers have had a chance to piece together a three-game winning streak.

Twice they’ve failed.

All the good vibes from Tuesday’s thrilling victory over Tampa Bay faded into the cold air Thursday night at Wells Fargo Center against a far lesser opponent, as the Florida Panthers won 3-2 in a shootout.

“We need to find a way to show up, especially at home in the first period. It’s huge,” Flyer captain Claude Giroux said.

“We need those points right now and we’re a desperate team at the start of the season, so we need those points.”

They need to stockpile some points before heading to Canada for back-to-back games next week against Toronto and Winnipeg. So picking up at least one was important.

Yet, you don’t want to be looking back in April and seeing how you threw points away against Buffalo, Washington and Florida when they were there for the taking.

Panther rookie Jonathan Huberdeau, age 19, won it during the shootout, the only part of Ilya Bryzgalov’s game that remains poor from a year ago.

“Sometimes guys, you gotta give them credit,” Bryzgalov said of Huberdeau’s backhand/forehand move. “They are skilled and working on some moves.”

Most of the Flyers placed the blame on a tepid opening period.

“I think that has been the story all year,” Matt Read said. “I don’t know what it is or how to fix it, but we have been coming out flat every game.

“Against Tampa Bay it was the first time we came out and we took control after the opening faceoff and we have to learn from that and take it to teams right away.”

Danny Briere said the leadership group talked specifically about building off the Tampa win and not allowing an early letdown against the Panthers, especially in the first period.
