 Ultimately, it was the Flyers lack of discipline and the resulting Islander Power Play goals that were the difference in the series.The series-winning overtime goal in game six was scored by Bobby Nystrom and assisted by fellow third liners John Tonelli and Lorne Henning.Nystrom's redirection of Tonelli's cross-ice pass from just above the Flyers left side face-off circle, floated up and over goalie Pete Peeters' blocker before the Philadelphia keeper could slide over to stop the puck.
