He's not alone.
Hampus Lindholm is 32. Elias Lindholm is 31. Nikita Zadorov is 31. McAvoy is 28. Zacha is 29. Morgan Geekie turns 28 on July 20. Swayman is 27.
"We didn't achieve nothing," Pastrnak said. "Like I said, yes, positive was that we made the playoffs, especially with the Atlantic Division was so tight and everybody winning the games. But at the same time, now you have long summer ahead of us, and you don't like that as a player. I'm sure you don't like that as a coach, so a lot of work ahead of us."
Even just two days removed from their final game, the questions started about next season, moves Bruins management could make with hopes of improving.
"As far as it goes with (general manager Don Sweeney) and management, every year I've been here they try and put us in the best position," McAvoy said. "They try and field the best team. They do that, they're committed to that, so I have no doubt that's something they'll try and do again this summer."
Zadorov said, "From my understanding, management's going to make adjustments into it and bring the right personnel again to benefit our system as well."
For now, though, it was a chance to be deeply disappointed in what might have been, but also savor a season few on the outside anticipated.
"We expected to be in the playoffs this year," Zadorov said. "I know you guys didn't, but we did in the summer and we did that. But we also could have went deeper, and I think that's what we have to look into it for sure and be more hungry next year."
And no matter what management does in the offseason, including with pending free agents including Arvidsson, and what those outside the locker room believe, the Bruins have seen what this group can do.
They believed in it at the start of the season. They believe even more now.
They will go into 2026-27, and the plan will be exactly the same.
"There is going to be same expectations," Pastrnak said. "There (are) two steps: make the playoffs and then make a run at the Stanley Cup. That's what I'm thinking of when I'm working out in the summers and that's my mental expectation. That's the only two really expectations you should have, coming into the season. That's not going to change."
