What we learned: Bruins persevere before self-inflicting

The Boston Bruins waddled through self-inflicted wounds in the opening twenty minutes of play against the Anaheim Ducks. Then they battled back from a 3-1 deficit and evened things up behind Brandon Carlo’s second-period marker and David Pastrnak’s third-period equalizer.

It seemed like the Bruins got past their turnover issues and Linus Ullmark’s struggles with rebounds. The Ducks barely established any momentum after Rickard Rackell, Isac Ludenstrom and Adam Henrique capitalized on Boston’s unforced turnovers during the opening stanza.

But, at the worst possible time, the Bruins committed their biggest mistake of the night.
