At the same time, they also know that this year is not last year. Nothing is guaranteed, as they found out in a Game 7 that they seemed destined to win -- but did not.
It is not easy to make it to the Stanley Cup Final. It is not easy to get over losing a Stanley Cup Final.
But on Saturday the Bruins seemed optimistic that they will start building toward something equally great, perhaps something even better.
"It's a new year," forward Sean Kuraly said. "We've got a new [dressing] room. We've got new digs. That's behind us. We've got a new year, everyone's got a clean slate this year. We're just trying to play good hockey and last year is all gone. We're looking forward."
That continues with the Ducks in town, a team that has also managed four wins in their first five games, a good start for a team that struggled last season.
Then the Bruins play three straight against their biggest rivals in the Atlantic Division, the Tampa Bay Lightning on Thursday at TD Garden and a home and home against the Toronto Maple Leafs, away on Saturday and in Boston on Oct. 22.
A Stanley Cup Final rematch looms against the Blues at home on Oct. 26. That might bring back a few memories.
Still, for now, the Bruins are only focused on the future, on getting through all the firsts of a season, all the milestones that bring a team to the meat of the schedule, that form the basis of a team that could turn into a championship-caliber club.
"We looked forward to doing this, just getting hockey back here at the Garden, seeing the fans again, playing in this building," Coyle said. "We love that."
The pomp is done. The introductions have been made. The players have been acknowledged. The last vestiges of last season have been left behind, relegated to the past.
"New year, new start," Coyle said. "[That loss] will stick with you. It will. But we have a fresh start to start something new. I think that's our focus. Just nice to be able to start fresh right now. Start from scratch and get another crack at it. We're excited about that."
