On paper, the Bruins had a perfectly respectable year: 100 points, a playoff spot, a roster with real names. It is the kind of season that invites a quiet offseason and a status-quo preview. That would be a mistake, because the number under the 100 is one of the more alarming in the league, and the reason Boston looked fine last year is a reason that does not tend to repeat.
| Metric | Number | The read |
|---|---|---|
| Standings points | 100 | Looks like a comfortable playoff team |
| 5-on-5 expected-goals share | 47% | Out-chanced most nights |
| Expected goals against | 278 | Chances allowed of a poor defensive team |
| Swayman goals saved above expected | +28.8 | 2nd in the NHL - the season was his |
The identity flipped
For a decade, Boston was defence first, a team that strangled the run of play and let its goaltending clean up the scraps. Last season the equation inverted. The Bruins controlled just 47 percent of the expected goals and, more damning, gave up 278 expected goals against, the profile of a genuinely poor defensive team. The offence was fine, powered by David Pastrnak's 100-point season and a plus-14 on-ice swing. The defending, the thing that made Boston Boston, was the problem, and no amount of scoring quite hid it, because the chances kept coming the other way.
One man made the math work
So how did a 47 percent team win 100 points? His name is Jeremy Swayman, and he had one of the best goaltending seasons in hockey. Swayman saved nearly 29 goals above expected, second in the entire NHL, single-handedly turning a leaky defensive team into one that finished with a tidy goals-against total. I have written about the goalie who edged him for the league lead; the point that matters here is what a season like Swayman's does to a team's record. It papers over everything. Boston's 100 points were, to a large degree, one man in the crease erasing a defence that could not do its job.
Why that is a warning, not a comfort
Here is the trap. A team that overachieves on goaltending looks, in the standings, exactly like a team that is actually good, and the temptation is to treat the 100 points as a floor and run it back. It is not a floor. Goaltending is the most volatile input in the sport, and asking any goalie, even a great one, to save 29 goals above expected again just to keep the team at par is not a plan; it is a wish. If Swayman regresses even to merely very good, and the defence in front of him stays a 47 percent group, last year's comfortable playoff team becomes this year's bubble, or worse. We watched Buffalo ride a similar wave of finishing and goaltending into a season that flattered it, and the lesson travels.
The offseason the numbers demanded
The work is clear, and it is not on the goalie or the top line. Boston needs to rebuild the defensive structure that used to be its birthright, the shot suppression on the back end and the two-way commitment through the middle that once made it the hardest building in the league to play in. Add scoring around Pastrnak all you like; it treats the wrong symptom. Until the Bruins are controlling play again rather than surviving it, the honest read on this team is not the 100 points. It is the 47 percent, and the fact that the man who hid it cannot be asked to hide it forever.
