The Bruins had a 2-o lead before the Islanders rallied in the second period. John Tavares scored 8:25 into the second to cut the Boston lead to 2-1 and Michael Grabner deflected Johnny Boychuk's shot in to even the score at 2. However, an error in judgement by Jaroslav Halak led to a goal by Kevan Miller with 3.4 seconds left in the period.
Boston added two more goals in the third.
"It wasn't our best effort that's for sure," Travis Hamonic said after the loss. "It just didn't seem like we could get any second or third efforts and extended zone time. Things are going to happen and every game isn't going to go as planned. You're not going to win every game, so we have to be better in Detroit."
The home team certainly did not get the bounces they got during Tuesday's 4-1 win over the Rangers and the Islanders did not have the effort they needed to out of the gate. The Isles outshot the bruins 45-33 but found themselves chasing Boston for stretches of the game.
And when the Islanders grabbed the momentum in the second, Miller's late period goal turned the game right back in Boston's favor.
"I thought we didn't play a 60 minute game, but I thought we played well enough to win the game," Islanders head coach Jack Capuano said. "Obviously the third goal was the turning point in the game. We were going good. The crowd and the energy. We were really dictating the pace in the second and then with four seconds left they get that goal."
It has been a rarity to see the Isles drop a game at home -- Thursday's loss was their fifth loss all season at Nassau Coliseum. The four other losses came against St. Louis, Montreal, Winnipeg and Toronto.
The Isles' big win over the Rangers earlier in the week set the stage for a "let down game," but Capuano doesn't believe that to be the case.
"I think our guys are real mature and past that," Capuano said. "I think we have a real good group in here."
Capuano did say he would have liked to see his team shoot the puck more.
"That was a little disappointing to me. We were down by two, you need a couple shots to try and get those second and third opportunities around the goalie. But we never really got the shot to the net," Capuano said.
