What Is Sign Stealing In Football?

In football, sign stealing is the process of decoding the signals shown on the other teamโ€™s sidelines in order to know what kind of play it might run before it happens.ย 

This is not a problem in the NFL, where plays are communicated to the offense via a communications unit inside of a playerโ€™s headset.ย 

But in college football and lower levels, where plays are often communicated via complex signs and codes, sign stealing could potentially yield a huge advantage for opposing defenses.ย 


As is the case in many sports, the details matter when it comes to accusations of cheating. Itโ€™s not necessarily illegal to break your opponents codes and steal their signs, but it does matter how you steal their signs.

If Team A cracks a sign code on Team B during a game, or in the ordinary course of preparing to play, thatโ€™s fair play. This is the case for many teams. If anything, Team B should be hiding its play calls better or utilizing a more complex sign code.
