Maybe this has been mentioned but one thing that sets him apart is his attitude and the fact that not a lot has been asked of him to date.
He stays out of trouble, he's grounded, noone really has bad stuff to say about him, he's not a pr!ck to his teammates or on the ice, he's not a dirty player, when he scores he doesn't dance and throw his gloves in the air ala Yakupov.
Also, he's on the third line hidden away from the scrutiny of the top 6 and producing beyond what is expected of that role. Which is how it should be at this stage. Granted, it's only 2 games but that 3rd line is producing like a 2nd line and teams are overlooking them cause they are simply 'a bunch of 3rd line rookies'.
He's gaining the confidence players normally get in the AHL, right here with the Montreal Canadiens and it's not going to his head.
