David Krejci couldn't properly celebrate his most important goal of the season in last night's 3-2 overtime victory against the Philadelphia Flyers in Game 2 of the Eastern Conference semifinals at the Wells Fargo Center. Krejci enjoyed delayed gratification well after his one-timed slap shot from the slot sailed over the shoulder of Philadelphia goalie Brian Boucher at 14:00 of the overtime. Play continued until the next whistle. When the shot was reviewed, Krejci was awarded his fourth goal of the playoffs, one that sent the Bruins home with a 2-0 lead in the best-of-seven series. "At first, I thought it was in, but they kept playing and finished the shift and that's what happened," Krejci said. Philadelphia was dominating the overtime period, limiting the Bruins to ineffective breakouts. That changed when first-line right winger Nathan Horton kept the puck in the Philly zone along the boards near the blue line. Horton skated toward Boucher but slid the puck to Krejci in the high slot. Krejci aimed, fired, scored — and watched in disbelief as the play continued. "(Horton) picked it up and made a nice play," Krejci said. "I wanted to get a good one-timer, and it worked. The line of Krejci, Horton and left winger Milan Lucic was not a dominant force in the team's seven-game series with Montreal in the first round. But it left its imprint on that series during overtime. Horton scored the overtime winners in Game 5 and Game 7 against Montreal and laid a sweet pass on Krejci's tape against the Flyers for his second assist of the playoffs. "I don't know what to say but that it happens," Krejci said. "In the first series against Montreal we got two (overtime goals), but other than that we didn't really put our names on the scoresheet too often.
