On April 26, 1975, a 26-year-old rookie Islanders goaltender named Glenn Resch, better known as Chico, leaned down to kiss the goal posts several times during a Stanley Cup playoff game at Pittsburgh Civic Arena, better known as the Igloo. Trying in vain to win Game 7 of a quarterfinal series and avoid a dubious place in history, the Pittsburgh Penguins had come hard at Resch early in the game, ringing two or three shots off the posts. But the Islanders went on to win, 1-0. 'I didn't do it to be a hot dog,' Resch, now a popular commentator on Devils' telecasts, said Thursday in a telephone interview. 'When you were on the roll like we were on, you're almost giggling. You can't believe this is happening.' That night, the Islanders joined the 1942 Toronto Maple Leafs as the only teams in NHL history to win a best-of-seven playoff series after losing the first three games. Much to Resch's delight, no team has matched the Islanders' comeback since. It was, he said, quite an accomplishment. The Philadelphia Flyers have a chance to join the exclusive club Friday in Boston, when they play the Bruins in a series the Flyers trailed three games to none. The Flyers are on the kind of roll the Islanders were on in 1975. 'The adversity we've faced -- I feel like we're conditioned to it now,' Philadelphia coach Peter Laviolette said Wednesday after Game 6, which the Flyers won at home, 2-1, to tie the series, 3-3. Although the Flyers said after the game that there was still work to be done and that they were far from satisfied with just tying the series, they were ebullient. The 1979 Michael Jackson song, 'Don't Stop 'til You Get Enough,' bounced off the walls in their dressing room. 'When you're in a do-or-die situation, you've got to find something else to give,' the veteran Philadelphia defenseman Chris Pronger said. Despite a staggering series of injuries -- the most recent to their goaltender, Brian Boucher -- the Flyers are getting the kind of breaks that Resch, among others, said they needed to overcome what once looked like an insurmountable deficit. The Bruins seem to be shaken. 'As you rack up the wins, you feel better and better about your game,' Philadelphia forward Danny Briere said. The Flyers last won the Stanley Cup in 1975. After recovering from a 3-0 deficit to beat Pittsburgh in seven games, the Islanders lost the first three games of a semifinal series against the Flyers. But then the Islanders won three straight games -- again -- to force a seventh game. The deciding game was at the Spectrum on May 13, 1975. Resch remembers it was loud. The Flyers were the defending Stanley Cup champions, and they did not want to be ousted by the upstart Islanders, especially at home. That is not always a good thing. 'The adrenaline you get from the fans can sometimes push you over the top,' Resch said. 'Boston is going to have a much tougher time putting their emotions in balance.' That day in 1975, the Flyers recaptured the magic. Resch gave up a goal on a shot that he was sure he had stopped with his stick. But the crowd was cheering. Resch looked at his stick, and the puck had torn out a chunk of his stick blade. Then Rick MacLeish scored on a wrist shot over his shoulder. The Flyers won, 4-1, then beat the Buffalo Sabres, four games to two, for their second straight Cup. Resch would win 231 regular-season games and 17 playoff games in his career, but he always has looked at those two Game 7s in 1975 as the high and low of his career. His broadcast partner, Mike Emrick, likes to refer to the breaks as 'the unseen hand.' The Flyers have been benefactors. In overtime of Game 4 last Friday, with the Flyers facing elimination, a rebound popped onto Simon Gagne's stick, and he scored the winning goal. 'When you don't have Lady Luck, that unseen hand, working in your favor, you get very nervous and very discouraged,' Resch said. The Bruins practiced for an hour Thursday, an unusually long off-day workout at this point of the playoffs. Coach Claude Julien said he felt as if his team was ready for the challenge of playing Game 7. But Resch, for one, likes the Flyers. He has been there. The unseen hand has helped him.
