That's what's so funny about this. Think about pro sports and ask yourself: what other league would not only allow this but actively practice it? What other league would call some random dude in off the streets to play in a game?
This would be like asking Dave from Orchard Park who played a little highschool football to come in and finish out a Bills game.
It's absurd that having an in-house emergency goalie isn't a thing. No player designated. No equipment guy or the goalie coach. No one. Go find me a goalie down at the rink, now!
