Doesn’t work from a logistics standpoint. The field is not flat. Football fields have a crown. If you lay down on the sideline and look across the field you will see only down to a person’s knees standing on the other sideline. This is for drainage. The crown has to be in the center of the field. To do what you suggest would require regrading the field and not only will that not happen, but it would prevent you from moving the field back to original position for L-L game.
