While others can debate if a healthy, productive David Krejci still exists (I certainly believe he does), this team was missing him last night.
The bruins were very assertive in the offensive zones for long stretches, the shot disparity shows this, but I also saw a lot of the team gripping the stick and almost anxious to score. McAvoy for instance had at least 3 very impressive moves to the net/behind the net that all sort of died on his stick at the end. Everyone was bringing the effort but they were missing a dose of finesse at the end.
To me, Krejci shines in these situations as he lowers the collective blood pressure/pulse of the team in these moments, and brings a bit more finesse to those last 1 or 2 touches on scoring opportunities. I think his presence in some of those o-zone moments last night would have been worth one more goal for the Bruins.
