From the most recent NCAA hockey rulebook. If I'm reading correctly, the referees have final call even if a skater is in the crease:
Rule 73 - Interference on the Goalkeeper
73.1 Interference on the Goalkeeper - The overriding rationale of this rule is that a goalkeeper should have the ability to move freely within the goal crease without being hindered by the actions of an attacking player. However, an attacking player’s position, whether inside or outside the crease, should not, by itself, determine whether a goal should be allowed or disallowed. In other words, goals scored while attacking players are standing in the crease may, in appropriate circumstances, be allowed. Goals should be disallowed only if an attacking player, either by positioning or by contact, impairs the goalkeeper’s ability to defend the goal.
Am I correct in interpreting that the bold italics allows the official leeway on the overturn and it's not automatic?
Now, looking at that video at the time contact is initiated. Turnbull is at the center of the top of the crease, but the puck is already well to Levi's right. Levi moves forward on his belly in a sprawling move toward the center of the top of the crease where Turnbull is - but again, the puck is clearly already past him. The only thing saving Levi is if his right pad can stop it. And oddly enough the only reason his right pad ends up as close to the puck as it ultimately does when Turnbull backhands is because after Levi collides with Turnbull, he is being dragged along with Turnbull toward the puck ...and Turnbull STILL gets it past his right leg and into the open space. Ironically enough if Turnbull was entirely outside the crease, it would have been a much easier goal to score IMO.
Am I being a homer in interpreting this? I leave that open as a possibility.
