In 2011, the Bruins won their Stanley Cup with a lockdown penalty kill, and a power play that bordered on comically bad. Stop me if this sounds uncomfortably familiar. Finding no reason to fix what isn’t (totally) broken, the Bruins are on much the same trajectory as they were two years ago, though the Blackhawks certainly should not take that as a cue to tempt fate by marching to the box as they have to this point in the post season. Furthermore, the Hawks finding a way to somehow take advantage of the Bruins’ penalty kill will go a long way toward mitigating the physical liberties Boston will no doubt plan on taking.
