For the first time since March 2016, the Bruins have dropped five consecutive games in a row, with a 3-2 loss to the Lightning on Thursday night standing as the fourth straight contest in which Boston has failed to capture any points in the standings.

For as much as the B’s had failed to cash in on these power-play chances for an extended stretch, they have at least peppered whatever goalie they’ve been matched up against during 5v4 sequences. In their previous four games entering Thursday night, the Bruins outshot the competition,  31-7, through 27:28 of TOI during the power play.

But on Thursday against the Bolts, any progress — as frustratingly slow as its been for the last few games — was negated by a brutal showing on the man advantage by the Bruins.

But in the pivotal moment of the contest, Boston constantly
