Tonelli's Islanders credentials are well-established. He played eight years with the club from 1978-86 and his 544 points are eighth all-time, while his 338 assists are sixth. His most famous assist? That came on Bobby Nystrom's Stanley Cup-clinching goal in 1980 - so it's fitting that he and Nystrom will be next to each other in the Nassau Coliseum rafters.
"It's an individual honor, but I don't have it without my centerman Wayne Merrick, Bob Nystrom, my right winger, and the rest of my teammates," Tonelli said. "I don't have anything without those guys."
Still, Friday night was about Tonelli, a man who waited far too long for his jersey to be raised. While only he and emcee Jiggs McDonald spoke, the lead-up to the event was a chance for his former teammates - and Islanders fans - to show their appreciation.
"He was a Tasmanian Devil on skates," Ken Morrow said in an interview before the event. "There was a relentless intensity to every shift that he played. Bar none he was the best corner man in the game. When he went into the corner there could be three or four opponents in there, but he came out with the puck and a lot of destruction was left behind."

But Tonelli was more than just a bruiser. The Tasmanian Devil was a three-time 30-goal scorer, with a 42-goal, 100-point season on the books in 1984-85. He also recorded 93 points (35G, 58A) in the 1981-82 season.
"He was a lot of fun to watch sitting on the bench, but he was even a better guy to have on my line when Bryan [Trottier] and I played together," Mike Bossy said. "One of my best seasons in the NHL was playing along Brent Sutter and Tonelli [in 1984-85]. One of their best years in the NHL also."
Tonelli had a knack for the clutch. Tonelli set up the dynasty in 1980 and subsequently saved it in 1982, scoring the game-tying and game-winning goals to power a comeback win in the decisive game five against the Pittsburgh Penguins. He had a knack for coming up big, even scoring the last-minute, game-winner to give the Islanders their record 15th straight win in 1982.
"For me, a lot of my memories center around what Johnny did, the big moments," Morrow said.
Head Coach Barry Trotz said the Isles' super stars had a third and fourth line mentality, and Morrow confirmed that Tonelli's work ethic set the tone for the rest of the Islanders.
"As a teammate, you felt guilty if you weren't giving that same effort," Morrow said. "There was no way you were going to come close to Johnny, but you felt that you had to get yourself going because there wasn't a shift that he took off in his whole career."
