Whether it’s boys or girls lacrosse. Many players try to push the limits on the pocket. Sometimes they string their own head and it isn’t even intentional. I don’t know if it’s the same, but every boys game, they randomly check lacrosse sticks for dimensions. Occasionally they find a stick that does not meet specifications. It might have stretched out during the season or the kid strung it wrong. I’ve never seen a game result challenged.

But I don’t know it it’s the same as a kid using a corked/illegal bat (is that still a thing) where they clearly know they are cheating.
