"Our inability to execute on the power play was the difference tonight," Lalonde said. "You get that many looks and to not generate a goal, that was the difference. It's frustrating because this game was very winnable. It was there."
After a scoreless first period, Philadelphia scored twice in the middle frame to take a 2-0 lead into the second intermission. The Red Wings applied pressure in the third, but a late empty-netter by the Flyers capped a game in which Detroit goalie Alex Nedeljkovic said "pucks just didn't sit right."
"Whatever it was tonight, we just couldn't finish," said Nedeljkovic, who stopped 19-of-21 shots in his first NHL start since Dec. 8. "Playing games like that, yeah we kind of shot ourselves in the foot a little bit. It's gonna happen, but we were right there."
The Red Wings, who could not get anything past opposing netminder Carter Hart, finished 0-for-7 on the power play. The loss dropped the Detroit to 31-32-9 (71 points) on the season, while Philadelphia (28-32-12; 68 points) swept the season series.
"You gotta learn how to flip some of these games," Lalonde said. "No matter what our roster looks like or the situation is."
