Though I do not agree with a good number voting that the rules with regards to the rouge should be changed at all, I think hardly anybody disagrees that somehow a return of a missed field goal that is the norm, not the exception, in Canadian football should be preserved and encouraged no matter what in any new rules.
Many casual American fans forget that the return of a missed field goal always has been a legal play in American football although less common due to shorter end zones. Of course it's the very same option when a kick is blocked whether the ball crosses the line of scrimmage or not.
Decades ago, with these respective rules of the kicking game each deriving from rugby and when the goal posts in American pro football were on the goal line until 1974 just like in rugby and in Canadian football always (as well as remain now in amateur American football before the high school level mind you), a missed field goal return also was a more common play in American football.
And NCAA college football fans will always remember the "Kick 6" of the Alabama-Auburn game, aka the annual Iron Bowl, a few years ago. Who in their right mind amongst my fellow Americans would not want more of that action?
