I've thought about this quite a bit and come down to this: The Boston Bruins organization has been highly successful in the NHL for the majority of the time this group has been together. I think it is both unfair and unwise to break up this group after one season that went significantly below expectations when injuries, player performance, and scheduling all played a role in shaping that outcome. That's not to say it's been a perfect hand for management, clearly not, but after years of deep playoff runs, father time and the grind of long seasons with shorter summers was going to catch up with the organization eventually.
You can't bury these guys after multiple cup appearances, a win, and President's trophy. Multiple down years merits a total overhaul of the management, but I think one bad year merits a more serious retooling of the roster before you make changes at the top.
