Should their lineup remain the same as it did in Game 6, the Bruins will suit up just three players without Game 7 appearances: Brandon Carlo, Joakim Nordstrom, and Karson Kuhlman.
"It's do or die. You've got to go out there and leave it all out there," Bergeron said of his message to those players. "I think it's a battle of will out there…it's whatever it takes and it's about poise and making sure you use that stress and nervousness the right way and feed off of it and use the energy that way. You need to make sure you still play the right way even though there's lots on the line."
Ultimately, the Bruins will be focused much more on what they can take from their Game 6 victory on Sunday afternoon. As Cassidy and many of his players pointed out, the 4-2 triumph at Scotiabank Arena was far closer to the identity of the team that finished the regular season with 107 points.
"We felt really good about or game," said Torey Krug, who notched his first goal of the playoffs in the win. "I think it was one of the more complete efforts, it was close to our DNA as a team. It' something we want to bottle and carry into the next game."
"To me, that's the recipe that has been successful for us most of the year, even in this playoff series," added Bergeron. "They're a good team that doesn't give you much. The space is very tight on the ice and when we simplify our game and bring it into their zone, that's where you want to play obviously. I think it's about doing a lot of what [we did] in Game 6, for sure."
In the end, though, there really is no way to script or predict what will happen inside the walls of TD Garden on Tuesday night. With both teams fighting to keep their Stanley Cup dreams alive, anything is possible.
"Game 7…it's what you play for," said Zdeno Chara. "Everything is on the line."
