Gorges shouldn't be on the PP, he has zero offensive awareness.
Beaulieu should've been played instead of Murray, speed on the back end is important when playing the Bruins plus he'd add an offensive element to the second PP unit.
That's completely on the coach, his lineup is clearly not clicking. He's out of touch with what's going on with the team. To start Murray yet again is stupid, as is sitting Briere for an obviously hurt Prust.
