The Boston Bruins struggled on the defensive end Thursday night, to say the least.

The B’s suffered one of their ugliest losses of the season at TD Garden, dropping an 8-5 decision to the Vancouver Canucks.

Bruce Cassidy wasn’t happy with his team’s all-around play against the Canucks, but the head coach made note of the penalty kill, which struggled to block shots throughout the contest.
