Yes it’s a serious post. First those are 4 players on a 25 man roster. Second you don’t have to blatantly say you’re sending a player down because they aren’t cheating. You could trade them as well. Third it’s virtually impossible to ignore information you’re given whether you want it or not.
Oh and btw this kind of sign stealing isn’t allowed in any shape or form. Didn’t seem to stop the coaches and FO.
