It is not 74’s job to come racing across the ice and play defense over on left side of ice. That’s not how that works.
For sure, he — and Caps bench - should be yelling to 44, if 44 is not noticing.
On the other hand, 44 is also supposed to recognize there are only four Kings in front of him. Where is their fifth player?
Further, it is not really correct to say 44 was “taking the puck carrier.“ Really, 44 was just retreating from the offensive zone, moving casually through neutral zone. He was halfway between puck carrier and cherry picker. The puck carrier was not a big threat in any way.
The main thing is to have awareness where all the Kings are and to keep them in front of you, if you are a D-man retreating from offensive blueline.
