If Wednesday’s Game 1 was any sort of indication as to how the Bruins-Maple Leafs series is going to go, you can expect this to be a quick one. The B’s swarmed the Leafs in an uncharacteristically relentless effort and took the opening game of the series at TD Garden, 4-1.
The Leafs took an early lead on a power play goal from James van Riemsdyk, but it was all Bruins from there. Wade Redden validated Claude Julien’s decision to put him in the lineup by tying the game on a slap shot that trickled past James Reimer, and it was Redden’s shot that was tipped past the Toronto goalie with 12 seconds remaining in the first to make it 2-1.
The B’s added second period goals from David Krejci  and Johnny Boychuk  to put the game out of reach, though Toronto coach Randy Carlyle stuck with Reimer the whole way. Both Redden and Krejci’s goals were stoppable, but the Leafs turned in a really poor effort in front of their goalie.
Tuukka Rask  didn’t have a very tough night and was able to stop 19 of 20 shots he faced. Van Riemsdyk’s goal came from a rebound tap-in out in front.
The series will resume Saturday at TD Garden.
WHAT WENT RIGHT FOR THE BRUINS
– The Bergeron line was absolutely buzzing for the Bruins. Tyler Seguin  and Brad Marchand  had three shots on goal apiece in the first period alone, with Seguin finishing the night with a game-high seven shots on goal. Though the B’s didn’t get a goal from the line, they almost got two. Seguin hit the crossbar/left post corner in the second period on a goal that was waved off, and Bergeron crashed the net to knock in a puck that was ruled no-goal because it had been whistled dead. If the Bruins get performances like that out of the Bergeron line, they’ll be sitting pretty.
– Where was Phil Kessel ? The former Bruin didn’t register a shot on goal until the third period. In 23 career games against the Bruins now, Kessel has three goals and six assists for nine points and a minus-22 rating.
– David Krejci  was a slow starter in the last two postseasons, but he kicked off the 2013 postseason with much better production. Krejci, who had two goals and two assists for four points in 11 first-round games over the last two seasons, scored in the second period and had a helper on Horton’s goal, which gives him more points (two) than he had in the first round against the Canadiens two years ago in a seven-game series in which he only produced a goal.
The most comical part of Krejci’s goal was that it started out as a bad play by the center, but the Leafs gave him an easy opportunity to correct it. Entering the zone, Krejci sent an ill-advised pass to the swarmed Horton, and the pass was broken up in front. Krejci was able to step over, gain control of the puck and wheel around to beat Reimer, who didn’t seem to expect a shot on net.
– The Bruins had three goals in only one of their last nine games of the season, and that three-goal performance on April 21 included an empty-net goal. They were able to get to three goals in just over halfway through the game Wednesday. Yes, they were playing a team that allowed the second-most goals of the 16 playoff teams during the regular season, but they also stepped up their game big time. All that talk of “not being able to flip a switch”? It’s bogus.
– With his goal, Nathan Horton  now has 18 points (nine goals, nine assists) in 22 career playoff games. Horton’s only other playoff experience came in the 2011 season, when he scored three game-winning goals and five others.
– The Bruins didn’t score on the power play against the Maple Leafs  in the regular season (0-for-7), but Horton’s goal came on the power play. The tally came following a shorthanded bid from James van Riemsdyk in which the Toronto left wing hit the cross-bar. The goal was reviewed to see if Horton, who tipped it in, had his stick above the crossbar at the time.
WHAT WENT WRONG FOR THE BRUINS
– While the top two lines were dominant for the Bruins, the third line was not. The trio of Chris Kelly  between Kaspars Daugavins and Jaromir Jagr had just one shot on goal in the first period, and each member had one shot on goal apiece through the first 40 minutes.
– The Bruins really got away with one when Andrew Ference  elbowed Mikhail Grabovski in the head with the Maple Leafs  already on the power play. With both players coming from different directions into the corner, Ference threw a high elbow that knocked Grobovski to the ground. Watching it live, it seemed like Grabovski was fishing for a call, but replays showed that Ference got away with a dirty play. Here’s the video .
– JVR strikes again. He’s had some big games against the Bruins in the playoffs in the past, and he could have had a second goal Wednesday had he not hit the crossbar. Van Riemsdyk led the Bruins with five shots on goal.
