"We need to be better," Marchand said. "Personally, I wasn't good the last two games. We can't be playing like that."
For Marchand, and for the top line, this has been an up-and-down Stanley Cup Playoffs. The numbers are certainly more than respectable -- Marchand is tied with the Blues' Jaden Schwartz (19 points) as the second-leading scorer in the postseason -- but they haven't been the consistent, dominating force that they have been in previous years, that they were in the regular season.

The team, instead, has been bolstered by its depth, by Charlie Coyle and Marcus Johansson, by Sean Kuraly and Joakim Nordstrom and the fourth line, by the goaltending of Tuukka Rask. It has gotten enough, but not more, from Marchand, Patrice Bergeron and David Pastrnak.
To win the Stanley Cup, the Bruins need that more.
The Bruins need the offense the Bergeron line has always provided consistently, and they need fewer mistakes, with Marchand and Pastrnak making uncharacteristic miscues in Game 2 when the Blues tied the best-of-7 series. Game 3 is at St. Louis on Saturday (8 p.m. ET; NBCSN, CBC, SN, TVAS).
It starts, as Marchand said, "with taking care of little details. That's the biggest thing. It'll come. That's how it is."
Not that that was the only issue for the Bruins.
"[The Blues] seemed to play with more urgency tonight than they did in Game 1," Bruins coach Bruce Cassidy said. "We played with less."
Marchand, who had four giveaways Wednesday, refused to blame their issues on things the Blues were doing. Instead, he said it was them. They were the line's errors and, thus, correctable.
"I think we can control the mistakes that are being made," Marchand said. "But that's hockey. Things happen."
