My bottom line. Football scoring isn’t broken, thus no need to “fix it.
...actually, field goal scoring needs to be fixed...for a team with a line of scrimmage inside the 15, a FG should count for four points, LOS from 15-23, three points, LOS from 24-33, two, and LOS 34 and beyond, only one...that would really shake things up, and not fundamentally change the game...
I think on 4th down if you can punt it thru the goal posts that is 3 points. Otherwise it is a normal punt.
