Jahmyr Gibbs stirred up a controversy by posting a photo that contained info on the Lions' protection calls, but Dan Campbell isn't sweating it.

Lions RB Jahmyr GIbbs posted a picture on social media of teammate Jermar Jefferson that included more than a dozen of the team's protection calls

While the code words help disguise what the Lions are running on a play-by-play basis, teams can identify tells and tendencies simply by watchng the tape. As a result, Campbell knows that a lot of what the team likes to do is not a secret.
