Thank you! I like to have nice debate when there is respect.
I personnaly see two reasons, but maybe there are more. For those scenario, let's say there is Team A and Team B. Team A starts with the ball.
First scenario. Let's say Team B is in field goal position, on 4th down. Should they kick it, or should they try to make a touchdown? Well, that depends on what Team A did. If Team A scored 0 points, than Team B can choose to kick it. If Team A scored a touchdown, then Team B knows they have to go for it, or they lose. It Team A scored a field goal, then Team B can decide if they want to play risky, and finish the game with a touchdown, or if they prefer to continue with a field goal. If Team A is in the same scenario, they do not have that info, so they have to guess.
Second scenario is in case of defensive points. Probably everybody would agree that in case of defensive points, the game is over, and I do agree with that. But that gives Team B an advantage, because if Team B defense scores points, then Team A defense does not have the opportunity to do the same. (Because anyways, even if we give the ball to Team B offense, they would simply kneel down 4 time).
Do these reasons outweights the good this new system would bring? I personnaly don't know, and I do think they should talk about it in the NFL. My argument was more that there were no perfect solutions that are completly fair. In some game, like in Bills-Chiefs, it would probably be more faire to give each team a possession, because the way the game was going, the probability of a touchdown was pretty high. In some other game, it is maybe more fair like it is right now. But when they are making the rules, they have to choose one system that is applicated to every situations.
PS: Sorry of my argument is not clear, English is not my first language
