A couple of observations from an outsider:
1-You can tell when Murray is tracking the puck well and when he's not. When he's not, he's off his angle and too deep in the net because he doesn't have confidence of where the shot is going.
2-Why does Rielly go deep into the offensive zone so much? It's like he's decided he's a forward now. I understand that offensive defensemen jump into the play from time to time, but it seems like Rielly's way too often going behind the opposition red line and vacating his D position.
