The Boston Bruins need a tweak or two. That’s undeniable what they don’t need is a large scale or large salary swap out. Injecting the wrong player, or removing one who is a key contributor is counter productive. It amounts to pouring sugar in the gas tank in the final smoke test before a race.
So who are the key components? In any order you care to put them the core of personality, ability and on ice impact are: Zdeno Chara, Milan Lucic, Patrice Bergeron, and Tim Thomas. Each of these four is a huge part of the teams identity.
Bergeron is the every thing man on the team. He hits, he blocks shots, he scores he makes passes and plays in all three zones and all situations. Zdeno Chara is the Zeus upon Olympus tossing down titans and defending what’s his in a way no one else can. Tim Thomas is an emotional catalyst, an elite goaltender and capable of stealing games and series. Milan Lucic is a monster, when he’s got his legs he’s the heartbeat of the team. His physicality spreads up and down the line up.
Each of these guys would be very difficult to replace with any other single player. Bergeron for Toews is passable, but the Blackhawks wouldn’t part with their captain, and the trade improves neither team significantly. A Lucic for Perry trade would be a similar level of physicality, and an offensive upgrade but complicates the already neck deep center position and greatly weakens the Bruins left wing.
Rick Nash is a goal scoring forward who’s having a down year, and also has a huge contract. He’s not especially physical, so flipping him for Lucic means a loss in one category for a noticeable but not really needed upgrade in another. Swapping him for Krejci probably means you end up with a line with not enough pucks to go around unless you’re looking at Lucic left with Nash sliding to center and a role player at right wing, much as say Byron Bitz is filling with the Sedins.
When a team has an identity, and success changing it’s core or threatening it’s identity is not how you make it better. The teams in the NHL that don’t have an identity aren’t very successful. The Montreal Canadiens this year are to put it kindly, in flux and need to figure out a recipe for success and hold on to it. Similarly the Washington Capitals have no unified identity and most of the best known players play like individuals. Trades for a team that has held the first spot in their division for most of the season, have some good prospects in juniors college should be players that compliment or enhance who the team already is, not radically change it.
Assuming the Bruins are adding a forward, it should be someone with a bit of snarl to their game, reasonably similar ability to Horton and good size. Ideally they would develop similar chemistry to Lucic and Horton, but other pairings are possible. In the unlikely event they developed a bromance that rivaled Jared Knight (@JKnight97) and Ryan Spooner (@RSpooner2376) so much the better, having more than one player you sync with on the ice never hurt a team. A defenseman is probably needed as much as a forward for depth. Since a certain Bean Pot champions captain is unlikely to be available, they need someone who can come in like Adam McQuaid and push other players to be better. For my money guys on expiring deals, or reasonable deals with one year remaining make a whole not more sense than big name guys.
