They got four shots on goal from Bergeron, topped only by the five from David Krejci. That included one 2:50 into the first period, when Bergeron got a chance in close on Bobrovsky. He had another redirect off Torey Krug that the goalie trapped between his pads.
But there were no goals. There were no points.
And that is where the Bruins need more, having been mostly pushed to this point by some unexpected depth scoring, from Charlie Coyle, from Marcus Johansson, from their fourth line.
"Is it sustainable? I don't know," Cassidy said, of continuing to lack production from his top scorers. "I can't predict the future. I'd like to think they're going to have to score. Obviously, some of that starts on the power play. We had one that was not very good - the second one, we got taken off it, so that's not even really a power play.
"We're going to have to figure something out as a group."
The postseason numbers don't look awful. Marchand has 9 points (4 goals, 5 assists), Pastrnak has 7 (3 goals, 4 assists), and Bergeron has 5 (3 goals, 2 assists). But none of those three has been consistent, and virtually none of that production has come in the three games of the second round.
That has been especially true for Pastrnak, who started the game on the third line with Coyle and Johansson, in attempt to lighten his defensive load and jumpstart his game. He was returned to the first line, with Bergeron and Marchand, at the start of the third period.
"He's trying to get inside," Cassidy said. "He's trying to score goals, play his game, still be a good 200-foot player in other areas. [Pastrnak]'s going to play with [Bergeron] at some point in the game. It's inevitable, generally speaking, unless everyone's going perfect."
