It's the most wonderful time of the year.

For the two teams still playing for the Stanley Cup, that is.

However, things are different for the league's other 30 representatives. General managers and other personnel types are busy in those NHL cities tinkering and toying with rosters to make them worthy of the Cup chase this time next year.

Some machinations will be more drastic than others, and the B/R hockey team took a look at the organizations most likely to make the most noticeable changes—thanks to age issues, draft opportunities, salary-cap constraints or other concerns.

Take a look at what we came up with and drop a thought of your own in the comments.

Boston Bruins

What a difference two months make.

As the first week of April arrived, the Boston Bruins were ready to wrap up a historic regular season and enter the playoffs as the odds-on favorite to hoist the Stanley Cup.

Then came the Florida Panthers.

Losing a 3-1 lead to the upstarts from Sunrise was bad enough, but even worse is the prospect of the Bruins heading into 2023-24 looking significantly different.

If nothing else, having 10 free agents—eight unrestricted and two restricted—less than $5 million in projected cap space and a single pick in the first two rounds across the next three drafts will keep GM Don Sweeney up nights for the foreseeable future.

Trade-deadline arrivals Dmitry Orlov and Tyler Bertuzzi are probably goners after their short stays in New England, while the likes of Taylor Hall and his $6 million annual price tag could be available for interested takers to allow for the signing of RFA goalie Jeremy Swayman.

Word on the street these days is Vezina finalist Linus Ullmark could be dealt to open the job for Swayman and offload another $5 million salary.

And the doomsday scenario for long-term fans is the goodbyes that could be needed for veterans Patrice Bergeron and David Krejcí, who could retire after 2,326 regular-season games in spoked-wheel sweaters.
