The Boston Bruins have definitely been playing better hockey under Joe Sacco, they currently sit first in penalty kill since Sacco took over, goaltending and team play has been way better, but they need to find a way to get their power play going.
One big reason their power play has not been producing is due to David Pastrnak having a down year. If the Bruins could find a way to get Pastrnak going this could fix all their problems on the power play.
Now the Bruins are preparing to face some playoff teams, and they will need their power play to do something for them or it could make the difference between winning or losing.
