If this is not an indication for application of Rule 17 what is?

omg they are not going to replay the game. Hope you’re not serious

No, but if something illegal were discovered, i.e. official bet on the game or took a bribe, they certainly could use the rule to replay the game from the point of the missed penalty.

This has been done once before. Iirc, it was at the end of a Seattle-Packers game where everyone had already gone to the locker rooms and the teams were called back out on the field to redo a play.

This would be different because it's never been done for a playoff game and well after the game is done. I think this is a good case for using the rule, but the NFL should have called the officials and told them to stop play and restart from when the penalty should have been called.

I really think if the NFL had called the officials and ordered them to restart from that point, most fans would go along with that.
