So the Islanders are pretty good right now, undefeated in regulation through seven games.

Well, when Bryan Trottier was an Islander, the team didn’t lose for 15 straight games. And they did it three times while Trottier roamed the ice like a mustached shark during his 15 years with the team from 1975-90.

When Trottier was at the Coliseum, the Islanders were a dynasty. They were unbeatable. They were the class of the league. And today, Trottier returns.

Trottier’s No. 19 jersey is being retired this afternoon prior to the 6-0-0-1 Islanders’ tangle with the San Jose Sharks (2-1-2-1) at 1 p.m. as part of a gala ceremony to welcome back the best all-around player in Islander history.

“It’s more fun than anything,” Trottier said yesterday at the Broadway Mall in Hicksville. “It’ll be fun tomorrow and it’s something that’s been building and building.

“It’s great for the fans and I’m excited to say thank you to them.”

A 1997 Hall of Fame inductee, Trottier is the only Islander to win the Hart Trophy, which he was awarded in 1979 as the league MVP. The glass-eating center who led the Islanders to four straight Stanley Cups during the early 1980s also collected the Calder Trophy in 1976 as the NHL’s top rookie, the Art Ross Trophy for leading the league in scoring in 1979, and the Conn Smythe Trophy in 1980 as playoff MVP. He is the all-time leading Islander scorer with a gaudy 500 goals and 853 assists for 1,353 points.

Trottier’s No. 19 will join Denis Potvin’s No. 5, Clark Gilles’ No. 9, Mike Bossy’s No. 22, Bob Nystrom’s No. 23 and Billy Smith’s No. 31 high above the ice of the arena known as Fort Neverlose when those six wore blue and orange.

The Coliseum, like it did last Saturday, will be rocked to its foundation as the memories start flooding back.
