How is that Quick's fault? His job is to keep his eyes on the puck. He can't cover a guy standing at the far post. That's the defense and forwards. They are the ones that should be covering Morrow.
I'm not placing all the blame on Quick, but he had no clue where the puck was. He was looking to the other side and playing 2 seconds after the goal was scored. Then when everyone slowed down and celebrated he looked and saw the puck was in the net. It's a theme for him.
