Boston has scored at least three goals in each of its last five games for a total of 17. But Cassidy believes there is room for more consistency throughout the lineup and, as a result, is still tinkering with his combinations.
"The lines are fluid right now," said Cassidy. "We're looking for what's going to be the best for the group without ripping everything apart. We know [Patrice] Bergeron, [Brad] Marchand, and [David] Pastrnak have been arguably the best line in the National Hockey League.
"Do we want to spread some of that around, do we want to be top heavy? Those are the things we're tinkering with. That's a group collaboration, including our top-end players that have been around that we respect their opinion.
"After that, we're going to see how it shakes out. The best players will play and hopefully they're in the right spots and combinations."
While Boston has received plenty from its top trio of Bergeron, Marchand, and Pastrnak, the Black & Gold has struggled to find much secondary scoring.
"That's where we're trying to get the secondary scoring from, where it doesn't come naturally," said Cassidy. "The Marchand's of the world, it's built into their DNA. Other guys maybe need to channel their youth a little more when they were offensive players, without chaining the whole dynamic of their game.
"Everybody in the room is capable of scoring goals, even if you're not labeled as a goal scorer. That's kind of the mentality. We'd like to create a little more anxiety in front of the other team's net."
