Mason Lohrei trade rumors are heating up again, and this time the timing may matter as much as the player involved.
The Boston Bruins are reportedly receiving calls from NHL teams interested in Lohrei as training camp approaches. The important distinction is that Boston is not believed to be aggressively shopping the 25-year-old defenseman. Instead, other clubs are circling back and checking whether Bruins general manager Don Sweeney is willing to listen.
That makes this a fascinating situation.
Lohrei is young, 6-foot-5, mobile for his size and capable of moving the puck. He also carries an affordable $3.2 million cap hit for the 2026-27 season before becoming a restricted free agent. Those attributes are exactly why teams should be calling, and exactly why Boston should not be in a hurry to give him away.
But with the Bruins carrying one of the NHL’s deepest collections of experienced defensemen, there is a legitimate question Sweeney has to answer before opening night:
Would Boston be better with Mason Lohrei, or with the forward his trade value could potentially help acquire?
Why Mason Lohrei Trade Rumors Are Heating Up Around the Boston Bruins
Boston Hockey Now reported, that teams have been checking on Lohrei’s availability because of the Bruins’ surplus on defense.
One NHL executive said Lohrei remains a player Boston could potentially consider moving.
That isn’t an entirely new development.
Lohrei was reportedly part of Boston’s previous pursuit of Rasmus Andersson, with the Bruins discussing a package involving Lohrei and a first-round draft pick. Andersson eventually landed elsewhere, but the discussions were significant because they showed Boston had at least been willing to use Lohrei as a meaningful trade asset.
The latest report doesn’t confirm Lohrei will be traded.
It does, however, reinforce the earlier indication that he isn’t necessarily untouchable.
Boston’s Crowded Blue Line Creates a Real Trade Decision
This is where the rumor starts making considerably more sense.
Boston’s NHL defense group includes Charlie McAvoy, Hampus Lindholm, Nikita Zadorov, Will Borgen, Henri Jokiharju, Connor Clifton and Lohrei. Boston also has additional organizational depth pushing for opportunities.
Lohrei himself acknowledged the competition during the offseason, saying he has always enjoyed “pressure and competition.”
From my perspective, Boston shouldn’t trade Lohrei simply because it has too many defensemen. That’s selling from a position of weakness disguised as depth.
The Bruins should move him only if another club values his age, offensive tools and contract enough to solve a bigger roster need.
That’s an important distinction.
A mid-round draft pick would not interest me much if I were Sweeney. Boston is trying to remain competitive around David Pastrnak, McAvoy and Jeremy Swayman. Turning a 25-year-old NHL defenseman into a future lottery ticket doesn’t accomplish much.
Using Lohrei as the centerpiece or secondary premium asset in a deal for immediate offensive help is different.
What Mason Lohrei’s 2025-26 Season Says About His Value
Lohrei recorded seven goals and 19 assists for 26 points in 73 games during the 2025-26 regular season.
Perhaps more interesting was the dramatic swing in his plus-minus rating. Lohrei went from minus-43 in 2024-25 to plus-17 last season.
Plus-minus alone should never be used as a defensive evaluation, but a 60-goal swing shouldn’t simply be ignored either. It reflects a considerably different environment and season for both the player and team.
There are still areas of Lohrei’s defensive game that need improvement. His underlying expected-goal results also weren’t dominant last season, which is one reason I would stop short of valuing him as a proven No. 2 defenseman.
But that’s not what acquiring teams would be paying for.
They would be buying the possibility that a 25-year-old, 6-foot-5 defenseman with puck-moving ability hasn’t reached his ceiling yet.
That has real NHL trade value.

Mason Lohrei Trade Value Index
My valuation of Lohrei lands considerably higher than a routine depth defenseman but below the level of a legitimate young star.
NHLTradeRumor.com Trade Value Index: 79/100
The factors pushing the number upward are his age, NHL experience, size, offensive ability, $3.2 million cap hit and remaining team control.
The biggest factor holding it back is that Lohrei has yet to establish himself as an unquestioned top-pair or high-end shutdown defenseman.
My projected trade-value range would therefore be:
A late first-round value in the right market; a quality young prospect plus another asset; or, more realistically for Boston, an important piece in a larger package for an established NHL forward.
That final scenario is the one that makes the most sense for the Bruins.
The Salary-Cap Reason Boston Could Consider a Lohrei Trade
What Trading Mason Lohrei Could Do for Boston
Boston currently projects to approximately $5.39 million in 2026-27 salary-cap space. Lohrei carries a $3.2 million cap hit.
In a simplified transaction where Boston traded Lohrei without receiving salary back, the Bruins would move from approximately:
$5.39 million → $8.59 million in theoretical cap room.
That doesn’t mean Boston needs to trade Lohrei for cap purposes. The Bruins aren’t facing a major cap emergency.
Instead, the significance is optionality.
Removing Lohrei’s $3.2 million contract could give Sweeney the financial flexibility to pursue a significantly more expensive forward if the right player became available.
That’s why I think the real question isn’t whether Boston can afford Lohrei.
It clearly can.
The question is whether his combination of trade value plus cap space is more useful to Boston somewhere else.
Should the Bruins Actually Trade Mason Lohrei?
For me, the answer is only for immediate NHL help.
Lohrei still has enough upside that Boston could regret selling him simply to clear its defensive logjam. A big, mobile defenseman entering his prime on a manageable contract is not an asset you discard because your training-camp depth chart looks crowded.
But if another team sees Lohrei as a potential top-four defenseman and is prepared to send Boston a legitimate top-six forward in a larger deal, Sweeney has to listen.
The Bruins’ defensive depth gives them that luxury.
And that’s what makes these Mason Lohrei trade rumors different from meaningless offseason speculation.
Boston doesn’t have to move him.
Other teams appear to want him.
That is exactly the position a general manager wants to be negotiating from.
