Let's look at what the Bruins could offer. Basically it has to be Hamilton.
Eriksson has negative value to a rebuilding club. Lucic and Marchand may have some value but they're both FAs soon, so IF Edmonton wanted them, they'd have to be sure they liked Edmonton and would want to re-sign which is far from a sure thing.
Picks, maybe, but the Bruins aren't likely to have anything in the top ten, so that limits the value.
They have some prospects but no one is that great. Subban is a nice goalie prospect, but goalies are really unpredictable. Then it's Koko, Spooner, Pastrnak, Morrow? No one that exciting but I guess a couple may turn to average players.
Bergeron, Rask, Krejci might draw interest but the B's aren't doing that.
Krug and Smith are nice players on ELCs / RFA deals but when paid market rate in the next few years are they going to be really valuable? Edmonton would just wait until they were ready to compete to sign those kinds of complementary pieces as UFAs. Ditto Soderberg.
Chara is too old and everyone else isn't too special.
Hamilton is the only star-level player who is still young enough to build around. I don't think the Bruins deal him given they need D just as much as they need forwards.
Nothing to see here.
Edit: OK, something insane could happen I guess like the Seguin deal. But it would be insane. Applying anything approaching logic to this, nothing should happen.
