I dont think it needs to be taken that far to were everyone needs to wear them. I think each team should have at least one extra one that way if a kid is at a tournament and gets a bloody nose that wont stop they can put it on for the next match. I have however saw a kid lose a match last year because of a bloody nose even after he had been wearing the mask the whole time. I dont see an advantage either way I know sometimes it seems like there maybe but i dont think there really is.
