Football games aren't allowed to include diving when linked with any football association as this is cheating and the respective FA's see it as bad to promote cheating within the game. This option refers to tendencies for slide tackles or standing tackles. So when players are set to 'dive into tackles' it means they'll slide more, potentially being dragged out of position and drawing numerous yellow cards. If the don't dive into tackles, they will stand off, or 'jockey' until the tackle has to be made. Against players with high flair and technique, these stand off players will be played around.
