I think they're necessary. Personally, I feel football is held back by staying the same. I think changes are needed to make the game better and more entertaining. I don't know what those are and drastic ones cannot happen overnight but there are some simpler things that could be done. I expect most of you to disagree with this as you probably want things to remain as they are. I expect so because I believe the football world is very conservative.
I'd like to read your thoughts about this and what you think should change.
My first thought concerns the field. As players have become more athletic the field has been made to look narrower because they're able to cover big areas more quickly than they did before. So I believe if fields were wider the extra space would really help the game in speed and rhythm.
Another one is about substitutions. I don't see why they have to be limited to three... what's the point? give more freedom to the coaches and make it so that even players that have come off the field can be brought on again.
I don't think these are big changes. They would not change the nature of the game and I believe they'd make it better... what do you think?
