Who needs a power play? Who needs a first line? Who needs a puck-moving defenseman playing up to his pay grade?

Not the 2010-11 Boston Bruins.

Despite all their blemishes, the Bruins gutted out an amazing 4-3 win over Montreal tonight in Game 7 of their Eastern Conference quarterfinal series at TD Garden. Boston will next face Philadelphia in the second round.

Nathan Horton, who also scored the game-winner in double overtime in Game 5, ripped a shot past Carey Price (who said it deflected off something) 5:43 into the extra session to earn the Bruins a win in a game they blew leads of 2-0 and 3-2 earlier.

Here’s a glance at the rest of the box score:

•Tim Thomas came up huge, with the only goals against coming on a shorthanded breakaway and two power play rockets. He finished with 34 saves.

•Chris Kelly scored his third goal of the series, while Mark Recchi and Johnny Boychuk also lit the lamp for Boston.

•The Bruins’ power play was 0-for-2 and finished the series 0-for-21.

•Milan Lucic set up Horton for the winning goal. It was Lucic’s second assist of the series — both on Horton game-winners — but the first line was still only Boston’s third-best line on the night.
