The play developed with center Lorne Henning sending a cross-ice feed in the neutral zone to Tonelli, who carried the puck just outside the Flyers blue line into the offensive zone with Nystrom. Tonelli made a perfect pass to the left side, where Nystrom quickly roofed it over Peeters to win the Cup.
"John Tonelli and I … if we didn't do 3,000 2-on-2s, it's just one of those days where it just worked out perfectly. Bob Dailey bit a little bit on John when he crossed over [the blue line], and I was able to get in behind him.
"But the thing I think about the most, and it's kind of the goat and the hero, I went in and I hit Bob Dailey really high and hard just before that goal. I always think if I had got a penalty there, I could have been the goat. I was just thankful that I was able to score that goal."
It was the beginning of a remarkable run that ultimately saw the Islanders win four consecutive Stanley Cup championships and 19 straight playoff series. They reached the Cup Final in 1984 before losing to the Edmonton Oilers in five games.
As part of the NHL's Centennial celebration, a blue-ribbon panel of broadcasters from NBC Sports Group, NHL Network, Sportsnet and TVA selected 64 moments. Fans can vote on them in a bracket-style tournament with four rounds, semifinals and a final.
Round 1 began last Wednesday and runs through Tuesday. The Greatest NHL Moment will be announced Dec. 16 at the Scotiabank NHL 100 Classic between the Montreal Canadiens and Ottawa Senators at Lansdowne Park in Ottawa (7 p.m. ET; NBCSN, HNIC, TVA Sports, NHL.TV).
After being upset by the New York Rangers in the 1979 playoffs, the Islanders were feeling pressure to get over the hump. Had Nystrom not scored in Game 6 against the Flyers and if the Islanders had lost that series, perhaps the roster would have been broken up.
