The NHL goaltender interference rule is just like the strike zone. It is subjective, often arbitrary. The rule/zone changes from game to game and from officiating crew/home plate umpire. A strike on Wednesday is a ball on Thursday, and a goal confirmed on Saturday is a goal reversed on Sunday.

There is no standard. It is preposterous. It is amateurish. Coaching decisions to challenge (or not) are essentially made in the dark.

I understand that a missed strike call that turns the count from 2-and-2 to 3-and-1 has implications. But there is an average of 290 pitches in a major league baseball game. There is an average of 6.08 goals scored in an NHL game.

There are more than simple implications from inconsistent, often nonsensical, goaltender interference judgments.
