for understanding how the rule is called, Goalie Interference, and headshots, seems to be the most baffling.
For why it is the way it is, Puck over the glass.
I understand why they did it, the tired defenders flipping the puck out to get a change and faceoff was pretty frequent. However, I would like to see it altered to an intentional act called, vs an unintentional act not being called.
Intentional a 2 min penalty for delay of game, unintentional there's no line change. Every puck clear since the rule has been instituted has been unintentional.
This isn't like a high stick where someone could get hurt, it's like a missed pass that turns into an icing. And there can be caveats with the rule, if no pressure from forechecker and the puck bounces and goes out... penalty, if there's pressure and it goes out and it's pretty clear the defender wasn't trying to flip it out, Face off and no change. An accidentally on purpose flip out is so obvious, an unintentional act is also obvious. Teams shouldn't be punished for accidental acts like this that don't cause bodily harm.
