Mike Bossy, an Islanders hero whose scoring prowess helped the team win four straight championships, died after a battle with terminal lung disease. He was 65 years old at the time.

Bossy’s condition was made public in October, when he took time off from his job as an NHL pundit for TVA Sports in French to cope with his health.

“The battle I am about to wage will not be easy,” Bossy wrote in an open letter. “Know that I will give 100 percent, nothing less, with the objective of meeting you again soon, after a very eventful hockey game. In my mind, you’ll never be far away. On the contrary, you will occupy a privileged place and you will be one of my motivations to get better.”

Renaud Lavoie, a former TVA colleague, was the first to break the news of Bossy’s death.

Before retiring with a persistent back ailment, Bossy spent his entire 10-year career on Long Island, acquiring a reputation as a franchise great and one of the best goal scorers the sport has ever seen. He concluded his career with 573 goals, including an all-time high of 50 goals in nine consecutive seasons. During the 1980-81 season, he famously equaled Maurice “Rocket” Richard’s record of 50 goals in 50 games.

Former teammate Chico Resch said of Bossy’s scoring, “He scores goals as naturally as you and I wake up in the morning and clean our teeth,” according to Sports Illustrated in 1981.

With eight All-Star appearances, three Lady Byng Trophies, the 1981-82 Conn Smythe Trophy, and the 1977-78 Calder Trophy under his belt, he was inducted into the Hockey Hall of Fame in 1991.

In October, former teammate Bob Nystrom told The Post, “He was, needless to say, a thin hockey player.” “That’s for sure,” says the narrator.

Despite playing at an age when fighting was accepted as a regular element of the game, Bossy was a vocal opponent of the sport, stating that he would never participate in a fight.

“The New York Islanders organization mourns the loss of Mike Bossy, an icon not only on Long Island but across the entire hockey world,” Islanders president and general manager Lou Lamoriello said.

“His drive to be the best every time he stepped on the ice was second to none.

Along with his teammates, he helped win four straight Stanley Cup championships, shaping the history of this franchise forever.

On behalf of the entire organization, we send our deepest condolences to the entire Bossy family and all of those who grieve this tragic loss.”

Michael Dean Bossy was born in 1957 to Dorothy and Borden Bossy, the sixth of ten children and the fifth of six sons. He was born in Montreal to an English mother and a Ukrainian father, and he met his wife, Lucie, at the snack bar of a midget hockey arena when he was 14 years old.

Bossy began playing for Laval National in the Quebec Major Junior Hockey League at the age of 15, and his 532 QMJHL points are still a record.

Bossy’s dislike of fighting was misinterpreted as a lack of toughness when he entered the NHL draft, and he was drafted 15th overall, almost opting for the World Hockey Association over the Islanders for financial reasons.

Bossy once told SI, “I didn’t think [Islanders general manager] Bill Torrey was offering me enough, and he reminded me that I was the 15th player drafted, not the first. However, I told him I deserved more because I was going to help him score goals.” Bill inquired as to the number of people. I told him, ‘Fifty goals.’

Rarely has a self-evaluation been so foresighted.

In a 1986 feature with UPI, Bossy said, “Whether in hockey or anything else — like learning French, cooking on a grill, washing my car — I am a perfectionist.” “It’s an obsession at times – I look in the mirror and think I’m insane.” That drive, on the other hand, has been with me my entire life. “One of the things that pushes me the most is the fact that I’m never content.”

His demeanor was frequently described as aloof. During his playing career, he was considered as a private individual, and because he spent his offseason in Montreal, it was said that he spent less time on Long Island than his teammates. Despite this, Bossy was a popular figure, and the Islanders honored him by lifting his No. 22 to the rafters of Nassau Coliseum just five seasons after his premature 1987 retirement due to a back injury.

Following his retirement from hockey, Bossy worked as a radio humorist on a French-language station, as a vice president for Titan, as a publicist and broadcaster for the Quebec Nordiques, MSG Networks, and, most recently, TVA.

His death is yet another setback for the Islanders, who had already lost three members of the 1979-80 championship squad, which launched one of the sport’s most illustrious dynasties, since January. Clark Gillies died in January, and Jean Potvin died in March.

The organization has been shook to its core by the triad of disasters.

Following Bossy’s diagnosis, coach Barry Trotz said of him, “He lives Islanders.” “And he’s definitely a legend on the Islanders….” I’m a little envious of him. I used to keep a close eye on him.”

Bossy leaves behind his wife Lucie, two daughters Josiane and Tanya, and two grandchildren.
