In my opinion, the D have been doing a decent job covering their areas of responsibility in the D zone. Its the forwards who have completely lost track of their assignments on numerous occasions. Lots of goals against have come from passes down low to guys who are cutting to the net from a high area. You can see the forward who is responsible for picking up that cutter just looking at the puck.
Watch Brown on the first goal last night - once the puck goes in the opposite corner, his new assignment is that guy in the high slot - he just watches the play...
And then Fraser on the second goal. I'm not sure if he came in on a change or he was just slow getting back in the play, but his assignment scored the goal, and he kind of floats in behind him while looking at the puck...
I saw the same thing from Kopitar & Richards in earlier games. Kings forwards need to work a little harder.
