Exactly, this is fixable for next season if they make the right moves.
Lindholm is here and frankly he's not going anywhere. Between his own NMC and his albatross contract, the Bruins are stuck with him. And I don't think current management has any desire to move him either. For whatever reason, they are infatuated with this player.
Let's just assume Marchand is back next year. To me, to get the most out of both of their skill-sets you need a RW who can both produce and play solid defensively and this becomes your No.1 defensive line. They get the toughest defensive assignments. I'd also like that player to bring an element of shooting and speed to that line. I have no idea who that is but I don't think that player is currently in the organization. Would a JT Miller fit here? Regardless of what I think of Miller as a teammate, all we really know for sure is how he fits on the ice. He doesn't do much to improve overall team speed but the guy can shoot for days, elite level shot and finish. Solid two-way player, that line can go up against any line in hockey defensively.
What if the line was Marchand - Lindholm/Miller - Miller/Lindholm. Lindholm can and has played RW. Miler has played all 3 forward positions. This team already loves having the guy taking the face-off always on his strong side. That line would be a menace on face-offs.
Then if Poitras is to remain at C, he's the fixture of line 3. Now you need to find two wingers for him, one of them absolutely needs to be able fly and make plays. Let's say that becomes Lysell who to me fits the bill now you need the correct LW for those two. If that isn't Trent Frederic (and I don't think it is because I'd like someone who produces and performs more consistently ), they would have to go outside the organization here as well which would be my preference. But we know Frederic is another player this organization loves so let's just assume he's extended for now. I do like how Frederic could protect the two young forwards.
Geekie - Zacha - Pasta - scoring line 1
Marchand - Lindholm/Miller - Miller/Lindholm - shutdown line 1
Frederic - Poitras - Lysell - the most sheltered line defensively
Beecher - Kastelic - Koepke - forechecking line
Jones, Wahlstrom, and Letteri don't have any trade value. Would they be able to parley Coyle +++ into Miller without subtracting from the group of forwards above? What would have to be added to do so? Do they need to cough up a 1st round pick? Should they? Would they have to subtract from the D-corps?
