The full first paragraph of the rule reads, “69.4 Contact Outside of the Goal Crease - If an attacking player initiates and contact with a goalkeeper, other than incidental contact, while the goalkeeper is outside his goal crease, and a goal is scored, the goal will be disallowed.”
So the next thing to figure out is what is the NHL definition of “incidental” is; Going by the dictionary definition, there’s no way it’s incidental contact. It was not a small part of the play, considering it was the primary reason Rask couldn’t move freely, nor was it by chance or because Hyman was pushed into Rask, it was Completely as a result of Hyman’s own actions.
Obviously it was judged incidental on the ice, but there is all the evidence in the real world to suggest they were wrong.
Also, I’m still waiting for anyone to explain how the MAF/Couture goal gets called back (and even given a penalty) but not this one.
