Change the scoring for field goals
yes, but your scenario is backwards; the point in football is to drive the ball towards the end zone, and the closer you get, the more a field goal should benefit you...line of scrimmage inside the 20, four points, inside the thirty, three points, inside the forty, two points, and 1 from forty to fifty...
No. Less points for close field goals would cause coaches to go for the TD perhaps and in any case there would be fewer tie games at the end of regulation.
