Okay. This is going to sound a bit crazy, but bear with me. I dislike how 98% of PAT's are guaranteed to go in. These kickers are trained to drive the ball 60 yards down the middle of the field goal. I propose a rugby-like extra point system where you kick from where the guy got the touchdown. So if the guy got the touchdown on the corner, they kick from there (but move it in 5 yards.) Then they can have an arch that backs the ball up to where it is more makable (so like at the 15 yard line or so for the corner to the 5 yard line for the middle. If the team opts to go for 2, they start at the 7 yard line except for if they scored within the hash marks where they start at the 2 or have the option to score at the 7.
The ball carrier can try to move the ball to the middle of the end zone however after he makes the touchdown, but if he is tackled, that is where the extra point is attempted from.
How does this change the game? Well first of all we will see a lot more 2 point conversion attempts. On top of that, it will bring back the drop kick. The percentage of PAT's made from the outside will most likely be higher with a drop kick. It would actually make the PAT an interesting play. It would also get rid of a lot of stupid TD celebrations.
My reasoning is I dislike the give me point after the TD. It needs to be as hard earned as the TD IMO.
