On a day off that followed an ugly Flyers loss in Montreal, Danny Briere huddled with Matt Read for a heart-to-heart Sunday. Other players talked among themselves or thought about Claude Giroux’s harsh message.

The Flyer captain’s demands for more effort in a postgame interview after the loss in Montreal came in loud and clear.

The immediate response was a Presidents’ Day transformation from a struggling team with all kinds of issues into one that mirrored their 2011-12 club that finished fifth in the Eastern Conference and a 7-0 shellacking of the New York Islanders in a Monday matinee at Nassau Coliseum.

“That’s how we gotta play, a full 60 minutes,” Giroux said after his first three-point showing of the season. “We didn’t let down and we wanted to win. I think we need more games like that where the four lines are going and everybody is playing well and we’re being physical.”

Giroux vented following a 4-1 loss in Montreal last Saturday night that left the Flyers’ 6-9-1 and 10th in the conference one-third of the way through this shortened season. He said players were going through the motions and not winning enough puck battles.
