Here's my understanding of NFL overtime rules throughout the years:
I'm not including turnover or safety scenarios in any of these. I could have an LLM fill in all the details but that's not how I roll. After all these changes it seems like there is still unhappiness with the system. Some prefer the college system which I don't understand that well. I didn't go to football schools. Well, a QB from my undergraduate college is/was an NFL head coach but it was a Division III school. I attended graduate school at University of Illinois: Chicago which hasn't had a football team in my lifetime. So I never got into college football.
Meanwhile soccer, or real football to many readers, uses a shootout system to break ties. Five offensive players try to kick a goal, 1:1 against the goalie. Whoever has the most points after those five turns wins, otherwise it's another five turns (as I understand it).
I get why soccer uses this system instead of another period. Compared to football there are effectively no breaks and the players are always moving. I'm not going to argue whether one sport takes more physical ability than the other, I'm not qualified to. As a casual fan, neither of these systems is perfect.
The NFL overtime system is very reactive. It's too easy to score in overtime so they keep tweaking it every time it's broken. On the positive side, it involves the entire team and mostly resembles the rest of the game.
The soccer system is a 1:1 matchup. It does not resemble the original game. It is very suspenseful and fun though. Some would like to see football adopt a similar system, to replicate these nail-biter endings.
Does everyone know that Sharp Shot on the Intellivision already figured out an exciting NFL overtime system?
For those unfamiliar, which is maybe everyone, Sharp Shot is a two player Intellivision game containing four brief mini-games. I ranked it #52. One of these mini-games is a 3-on-4 football competition.

The premise is simple - the center snaps the ball to the quarterback and immediately has to block the rusher. There are two receivers and two defenders. The quarterback has to try to make as many touchdown passes as they can within the time limit. Quarterback sneaks are not allowed.

Being an early video game, there are some limitations and oddities:

I think this could be adapted to a 3-on-3 overtime that would be extremely exciting while still resembling the original format of the game.
The rules would be:
This could also be a 4-on-4 game. Anything larger than that seems like too much.
One of the goals of this idea is reducing injuries. There should not be any high impact plays required. As noted, tackling the quarterback isn't necessary to end the play (and should be discouraged). The receivers would not ever be tackled unless they catch the pass outside of the end zone. There is no tackling on an interception either, the play is simply over.
This format would also be fairly quick. With clock stoppages these 30 second shootouts would go about 5 minutes. That's it, a fast-paced competition between the best players on each team to break the tie.
There are some downsides to this idea. We can all think of quarterback/receiver combinations that would score at least 7 times in this format. That might feel like it is going on forever. As someone who's lived in the Chicago area for a long time, I can also think of quarterback/receiver combinations that couldn't score once in this format if you gave them an hour. This system is biased against quarterbacks with strong rushing skills, it essentially takes away half of their skills.
I'm not going to argue this is perfect - I just think it would be fun, suspenseful, and over mercifully fast.
