All season long the Boston Bruins have searched high and low to try and find their “hard to play against” identity, and all season long they've only found it in fits and starts. So it’s fitting the Bruins built up a 3-1 lead in their playoff series against a beatable Toronto Maple Leafs team, and now find themselves staring down the barrel of a Game 7 scenario after losing both Games 5 and 6. The latest setback was a 2-1 loss to the Leafs at the Air Canada Centre Sunday night when a couple of mistakes in the third period sealed Boston’s fate, and their offense didn’t produce until Milan Lucic scored a goal 59:34 into the contest. It wasn’t a good enough effort from the Bruins in a potential elimination game. The Leafs out-hit the Bruins (58-50), blocked more shots (20-17) and took more pucks away (17-5) while winning all of the effort categories in Sunday night’s game. Bruins coach Claude Julien has watched many such “efforts” from his team this year just like the one in Game 6, and isn’t any more amused now than he was in March. “As I said to our players after the game, we’ve been a Jekyll-and-Hyde hockey team all year, and that’s what you’re seeing right now,” said Julien, who has been up in arms after games this season many more times than in years past. “I think it’s important for us to being the good Bruins team to the table for Game 7.” Perhaps no group of players embodies the “Jekyll-and-Hyde” moniker more than Patrice Bergeron, Brad Marchand and Tyler Seguin. After carrying the team for most of the regular season, they have hit a rough patch offensively against the Maple Leafs while also doing very little to impact the game in other two zones.
