The intent of "sudden death" from what I understand was not to make teams just "play defense". It was to shorten the game and have less wear and tear. It should also encourage teams to play for a win in regulation.

However the majority of coaches never seemed to get this logic and would settle for three, or kick an extra point instead of going for 2. Somehow you avoid criticism losing in overtime but risk getting blown up if you go for it at end of regulation and fail.

Should just have a draw as a final result then and only play overtime in the playoffs.

Lots of 4-6'es and almost no 8s or netter.

Others have mentioned that this will cause/allow defenses to do more holding. NFL likes their offense. I don't think it will pass.

In the grand scheme of true effect on the play, I'd probably order their severity as illegal contact < defensive holding < pass interference but they are always subjective, especially holding versus DPI.

I would honestly make them a 10-yard penalty, 10 yards + automatic 1st down, and 15 yards + automatic first down respectively but that's my 2 cents

For player protection purposes I'd be fine with that. Yeah, there'd be more ties but there'd also be very few teams playing for a tie. It would make the end more exciting for sure.
