In 1996, his goal gave the Pittsburgh Penguins a 1-0 win over Winnipeg I.
His goal Tuesday was his 16th career overtime tally, a new NHL record. He had shared the mark with Mats Sundin, Sergei Federov, and Patrik Elias.
Wayne Simmonds bailed out a shaky Ilya Bryzgalov, scoring with 9.7 seconds left in regulation to tie the score, 4-4. Simmonds tapped in a slick pass from James van Riemsdyk to send the game into overtime.
"He was wide open, and all I had to do was slide it over to him," van Riemsdyk said. "I was going to throw it at the [goalie's] pads, and I saw him at the last minute."
The Flyers outshot the Jets, 55-26, but needed the late heroics because goalie Ondrej Pavelec (50 saves) was sensational and because the Jets were 3 for 3 on the power play.
The Flyers' attack was relentless all night.
"We've got four lines, and every one of them can score," Jagr said. "You've got to make the other team tired."
"I'm really proud that the guys kept coming and kept pumping," coach Peter Laviolette said. "It was one of those gutsy efforts. Might have been one of our best, toughest wins of the year. We kept fighting and pushing to get the two points."
The 55 shots tied a Flyers record for most shots in a road game. They had 55 shots in a 4-3 OT win in Boston in 2007.
"That's what made us so dangerous in the first half of the season - any line you put on the ice can score," Jagr said. "Then we kind of switched [because] there were a lot of injuries. We have to go back to that. It doesn't matter how many they score against us; we know we can score a lot of goals."
The enigmatic Bryzgalov and the Flyers' penalty-killing units continued to struggle. The Flyers have allowed two or more power-play goals in three of their last five games.
With 15 minutes, 3 seconds remaining and the Jets on a power play, Evander Kane scored from above the right circle as Bryzgalov whiffed on his attempt to glove the puck. That put Winnipeg in front, 4-3.
"It was just a stupid mistake," Bryzgalov said. "I started catching the puck, but I miscalculated the distance between the puck and my glove; it hit me on the edge of the glove and went in. I'm kind of sick and tired of these mistakes. . . . Stupid mistakes."
His teammates bailed him out. That left Bryzgalov in a good mood as he kidded about the mocking "Illllyaaaaaaaa" chants delivered by Jets fans.
"It was nice to hear cheering, 'Ilya, Ilya.' I never heard it before," Bryzgalov quipped. "When 15,000 people support you, it's pretty impressive."
Just like at home?
"No, here they cheer me. In Philly, they boo me," the goalie said.
Earlier in the day, Bryzgalov injured his glove hand in the morning skate, but he was cleared to play.
As in most Flyers-Jets games this season, the scoring chances were abundant. The Flyers had more of them, but Pavelec was outstanding.
In one of the best saves of the season, Pavelec made a diving glove save to stop Jakub Voracek, who looked as if he had an open net until the goalie appeared out of nowhere while the Flyers were on a power play with 7:56 left.
But the Flyers got late-game heroics from Simmonds and Jagr to keep the Jets from climbing from ninth to third in the Eastern Conference.
