I don't think the point's structure needs changing at all, I just think it needs adding to.

 

I would do this:

 

1 pt - Standard extra point (as usual)

 

2 pts - conversion (pass or run, as usual)

 

3 pts - 58 yard field goal (ball placed on 40 yard line) - the game is evolving and kickers abilities have outgrown the rules, so this way the game is kept exciting and the kickers have a new challenge with a long field goal to contend with

creative, and not bad..

 

i would like something more exciting, i agree with not changing the point structure.. but adding something new.. maybe 1 play from the 10 or 20 to score for 3-5 points... i dunno
