The Bruins had an impressive win on opening night, but there was one area they have to clean up.
It might mean nothing to the Boston Bruins after their season-opening win, but the undisciplined penalties in the first two periods could've put them in a bad spot if it weren't for an outstanding penalty-killing night. While they killed all five penalties against the Washington Capitals' power play, it might not be as easy when teams get sharper as the season goes on.
