Don't know I'd have to check the CFL archives which I'm not going to do. And my guess it's not an issue of bemoaning, It's not even really an issue. It's more I would guess that location has come up now and then and is there anything the league could do with it to improve the game. Just like any other proposal, simply a discussion and not a solution looking for a problem.
For the record I'm not supporting any idea of moving in and out goalposts no way no how. However, thinking that moving the goal posts stationary to the back of the end zone would ruin the game's excitement of last minute point getting is a bit exaggerated. For example, one of the many things I like about the CFL is the last 3 minutes of each half that allows teams more time to get themselves into scoring position that makes virtually no lead safe. Having the goal posts in the back of the end zone would definitely make field goals more challenging but I could also suggest based on my observations that over time (with no stats to support) place kickers are more athletic, stronger and accurate than ever before.
It's fun to discuss these things knowing a lot of this will go nowhere other than a discussion.
