The Islanders came up short again in their second attempt at finishing off the Flyers, losing 5-4 in double overtime in Game 6 of the best-of-7 series at Scotiabank Arena in Toronto on Thursday.
Philadelphia defenseman Ivan Provorov scored 15:03 into the second overtime Thursday, two days after Scott Laughton's defection at 12:20 of overtime kept the Flyers alive with a 4-3 win in Game 5.
So the Islanders will have to try again Saturday in Game 7 in Toronto, the East hub city (7:30 p.m. ET; NBC, CBC, TVAS). The winner plays the Tampa Bay Lightning in the Eastern Conference Final.
"We've just got to go through a little adversity," Islanders coach Barry Trotz said. "One thing that you do as a team is you fight adversity and you grow. You grow as a group. So this is part of our process."
The Flyers also won Game 2 in overtime, pulling out a 4-3 win on defenseman Philippe Myers' goal. But the Islanders looked well on their way to reaching a conference final for the first time since 1993 when their 3-2 win in Game 4 on Sunday extended their series lead.
Teams with a 3-1 lead are 285-29 (90.8 percent) winning a best-of-7 Stanley Cup Playoff series, including 7-0 in the first two rounds this season.
But Philadelphia has proven to be resilient with its back against the wall. Now New York will have to be too.
"Obviously, we would have liked to end this thing tonight," Islanders forward Matt Martin said. "We'll just approach this next game [that] obviously, our season's on the line. If we put forth the effort we put out there tonight there tonight, I like our chances."
