The field dimensions controls appear at the bottom left and right of the play designer and the formation designer and allow you to adjust the position of the players as they appear on the designer field.  The field dimensions controls don’t move the players around the field they move the field around the players.

Move Line of Scrimmage

The move line of scrimmage up and move line of scrimmage down  buttons move the line of scrimmage and the players on the field up or down in the field view.  This allows you to position the players within the designer where it makes the most sense for the type of play or formation you’re designing.

Change Field Length

The increase field length  and decrease field length  buttons make the view of the field longer or shorter.  For most plays the field designer view will be big enough to accommodate all player routes and coverages but, if it’s not, you can increase the field length as needed.
