A surprising area of focus for the Pittsburgh Steelers in recent years has been to take every opportunity to allow your opponent to hurt themselves, and the primary way that they have accomplished this has been to utilize hard counts while on offense to cause the defense to jump offside.
Provided that he is not called for encroachment or is not unabated to the quarterback, the result will be a ‘free play’ in which the officials will allow the play to be run, with a flag being thrown. At the conclusion of the play, the offense can decide whether or not to accept the penalty based on whether or not the result of the play was more advantageous than the penalty.
