During game prep defensive players learn opponent's formations and keys to learn how to defend what play is being run. This is mainly done through film study. During game play they identify formation, then initial movements by their opposing player(s) they are assigned to. They give percentages of which play is being run out of certain formations & guess once initial movements occur. This is done with in-game discussion, iPad study & halftime adjustments. It is the offensive coordinator's job to disguise and lower the defense's ability to guess at a high rate. Our O.C. is terrible at disguises & adjustments, hence why these plays are not successful over & over.
