This is the reply I was looking for
Prevention of this problem is the biggest thing. Sometimes in big Schools this is a problem, but I think we must bring this up with coaches before the game so that this doesn't happen. Maybe if there are more than 1 number 12 for instance that we write it down somewhere and if there is an USC that we get a name as well to go with it (like writing down on a penalty sheet 12-jh or 12-bm. This sounds like a solution!
