The plan had never been to keep Pastrnak with Bergeron and Marchand. The thought was it made the Bruins too top-heavy. But they never gave Cassidy a chance.
"It was hard to break them up," Cassidy said.
And it has made all the difference for Pastrnak.
In six games against the Ottawa Senators in the Eastern Conference First Round last season, Pastrnak had four points (two goals, two assists). He had that midway through the first period in Game 2 this time around.
"He's got that confidence," Bergeron said. "He wants to be the guy. He wants to make those plays, and if we don't have the puck, he hunts it back. That's what amazes me with him. I think there's a lot of skilled players that are skilled when they have the puck; when they don't have it, they don't necessarily want it as much as this guy right here. So, I think he's taken a tremendous step this year by the way he plays away from the puck.
"We learn just as much playing with him than he's learning from us."
The tutelage of Bergeron, the preeminent two-way center in the NHL, and Marchand, no slouch himself, has been formative. The way the three talk has been significant in his development. That, though, seems to shortchange the pure talent that Pastrnak has, coupled with the drive to become a forward worthy of inclusion with Bergeron and Marchand, the way Marchand has been to become a partner worthy of Bergeron.
