In the NHL, or generally in ice hockey and similar sports, there is a statistic of GWG - game winning goals. A goal is a GWG if it is enough for a team to score only until this goal with no more goals in the game and still win the match. For example, if team A wins a match 5:2, their third goal was the GWG. It does not need to be the last goal scored.
Now, I want to ask, what happens if the GWG is an own goal? I know that in the NHL, the concept of own goals does not exist. But maybe in other sports like field hockey or floorball, even football, or in other ice-hockey leagues etc, what would happen then? Is it meaningful to talk about a statistics of GLG - game losing goals? It would be an own goal which is enough for the opposing team to win a match with it.
