Well I'll make a post here and I won't make myself popular. But that's okay I don't have many friends anyway.
Looking at the video, I think no goal was the right call.
I think we're basically on the unified rulebook now?
If a Goalkeeper, in the “act of establishing their position” within their Goal Crease, initiates contact with an attacking Player who is in the Goal Crease, and this results in an impairment of the Goalkeeper’s ability to defend their goal, and a goal is scored, the goal will be disallowed.
I got my wife to look at the clip, who is nominally a devils fan but doesn't really watch hockey. She said it was mariginal but there was contact inside the blue paint.
I will say though that there shouldn't be a Belfast official directing the refs on what to look at. That set up should be neutral and the same in all the rinks.
