well first off his dad passing away, that is awful and you can't predict the effect that might have on him. That said, he was playing poorly BEFORE his dad suddenly passed away.
I tend to look at how the goals are going in, specifically the part that the goalie can control. Right position, right angle, depth, square, rebound control, recover. All that sorta thing.
The big thing I see this year is that Murray's tracking is just not at the same level it was. Watch, when murray is tracking and focused (tracking is usually a focus issue) you can really tell on tips.
He will read that the shot is going to be tipped and square up on the person tipping the puck, not the shooter. I think most of what is going wrong with Murray this year is mental, last game, first goal was pretty dang bad, that was a focus issue. The back hander after that was in a good place and tricky because it's a back hander, but murray from last year would stop that. The blocker side shot from that pass from Vanek. I blame the defense, but Murray didn't read the pass and was very deep in net, he might not make that save anyway but just saying if he is tracking/reading the play his feet aren't where they where when the shot came in.
All goalies rely on anticipating the play to some degree, blocking style goalies like Murray even more so. When his focus/tracking comes back he will anticipate better and we'll see an improved product on the ice. I think Murray will come back to the level he was before, my only worry is that his lack of anticipation / tracking is some lingering effect from the Concussion. We've seen that before, where it takes a good number of games back to really get the brain working right again after a concussion for a goalie.
