The Bruins are clear about five of their seven defensemen. Zdeno Chara is their shutdown ace. Johnny Boychuk is the hard-hitting first- or second-pairing strongman. Torey Krug is the power-play specialist. Kevan Miller is the No. 6 stay-at-homer. Adam McQuaid is the one who can’t stay healthy.
There is less definition regarding Dougie Hamilton and Matt Bartkowski. It is because their ceilings correspond with their skill.
