I have never liked the returns aspect of football. Would like to take them out of the game.
Field goals/PATs - should either be makes or misses, they should not be able to be returned for points. PAT miss, no points, FG miss, turns the ball over.
Kickoff - out of bounds, penalty, out the back or rolls into the endzone, touchback at the 25, catch the ball you get it at the spot of the catch (no returning, no tackling allowed), if the catch is fumbled it is live, otherwise you take a gamble and get the ball where it stops rolling
Punt - out of bounds, get the ball there, out the back or rolls into the endzone, touchback at the 25, catch the ball you get it at the spot of the catch (no returning, no tackling allowed), if the catch is fumbled it is live, otherwise you take a gamble and get the ball where it stops rolling
