A bigger concern is Philadelphia's penalty-killing unit.
After allowing the Penguins to score twice on three power-play chances, the Flyers gave up three more on Buffalo's six opportunities.
"The penalty-kill right now, we've got to continue to look at it and work at it," Laviolette said. "Every day is a new opportunity. But we've got to get on track here and get a win in the column and get moving in the right direction."
They'll have to get it started on the road. The Flyers are in the middle of a stretch in which they're playing six of seven away from Philadelphia.
The Sabres did little wrong in rewarding their fans in coming out of the NHL lockout.
Before the game, Sabres players, coaches and team owner Terry Pegula were in the First Niagara Center lobby to greet fans when the gates opened. They handed out programs, signed autographs and posed for pictures.
Once the game began, Buffalo scored the first goal, courtesy of Ott. At the final horn, they gathered at center ice and raised their sticks to acknowledge the sold-out house.
The Sabres were without third-line forward Ville Leino, who is listed as day to day with a lower body injury after he was hurt in practice Friday.
Notes: At 18 years and 254 days, Sabres rookie C Mikhail Grigorenko became the fifth-youngest player to be on the team's opening roster. Pierre Turgeon was the youngest (18 years, 41 days) in 1987. ... The Sabres have only about 12,000 tickets unsold for their remaining 23 home games. ... Flyers C Zac Rinaldo played just 2:47 before leaving the game with what the team called a lower body injury.
