You can't honestly believe that.
He takes three strides between the red line and when the puck is on his man's stick in the slot. McDavid was caught deep. That man was his responsibility.
Maroon starts from the opposition blueline and passes him like he's standing still.
Ebs was strides ahead of the guy that scored. He slowed down to man the blueline which was his responsibility. Maroon was the first forward back and took the middle of the zone. One dman went to Seguin and the other covered the other Star. Then Maroon, who was the first forward back and already in the middle should have covered the middle like a C would and taken McD's role,, but he didn't. He left his position to skate and double team Seguin at the point, leaving the middle open .
If Maroon would have stayed in the middle as he should have, then Seguin would not have had a play to the middle, down low or to the other point.
If Ebs actually did what you say and went with the scorer then the point pass would have been wide open and Maroon would have been in no man's land
Ebs only fault is being weak defensively and not reacting fast enough to Maroon's decision.
