The Bruins have scored at least 100 points every year since 2018 apart from the shortened 2021 season, and I see little reason for that streak to stop now. Team speed and scoring look like being challenges, but they have a stacked defense, strong goaltending, size and hopefully grit and toughness. They should be tough to play against. The D is going to need to be better than it has been the last two years, but it should be.
I'm not seeing a dominant regular season team here - the offense just isn't there, IMO - and I expect the Leafs under Berube and the Panthers, despite having lost a few players, to be slightly better regular season teams. But that's ok. The Bruins should comfortably enough settle into a qualifying spot and only find themselves in any difficulty if at least two of the Sabres, Sens and Red Wings finally get their act together properly or Tampa somehow bucks their decline.
Overall I'm predicting a slow-ish start for the Bs, after which they pick up pace as they go. Add top 6 wing help at the deadline, wind up with about 105 points. From there it will depend on injury luck, the draw, and just how much they've learned and instilled about what it takes to play effective postseason hockey as to how they'll fare in the playoffs. They're not going to get by on speed and skill, they lack raw talent compared to some rosters, and I don't have them pegged as a tippy-top contender. But if they gel well, play tough, hard and disciplined, and everyone buys into the same mindset and direction, then you never know.
On the flip side I see four ways the whole show could fall off the rails - Pasta getting a serious long-term injury (God forbid), the D not meeting expectations and faltering badly, the middle 6 completely failing to get their act together and provide meaningful secondary scoring, and Sway getting major yips following an acrimonious summer. Any one of these could be fatal, all are possible if unlikely, or are otherwise in the hands of fate. Hopefully they are avoided.
Anyway, going to be an intriguing season, that's for sure.
