I'm not sure what the big deal is about the sign stealing. It isn't illegal and has been happening for years. With video technology and real time updates getting better it was inevitable that they were going to be stolen in real time. If you haven't checked out Mark Robers video on youtube about an app he made, you should check it out. Fairly simple but within a couple signs he could figure out exactly what a certain sign indicated. Either teams have to get smarter, or they eventually go a mic'd up system where no visual signs are given.
