I think he was in goal for Rick MacLeish’s game winner in the 1973-74 game six final. The Flyers won then and the next year, but not since. Gilles was a good guy. God rest him.
Honestly, Moose DuPont’s blast was on-target. Rick’s stick certainly touched the puck and caused the re-direction. From some angles it looks like it didn’t matter, but it did.
That was waaaay before my hockey history. I didn’t start watching until the Stars moved to Dallas.
