I think the big problem the NFL is facing is that they've likely never anticipated this situation. A player's life is threatened on the field, and what to do about the game. The logistics of moving a game 24 hours, all the TV, advertising, personnel, teams, equipment, venue, fans, tickets, etc. They do OK with a few days warning, like the Bills games moving to DET, but what to do about a game in progress? Let alone a game this big with huge playoff implications. A Bills forfeit would be the most expedient solution. Moving the game more than 24 hours impacts next week's games, so what to do? Like the line in Apollo 13, "This isn't a contingency we even remotely considered."
But nobody cares about all that. We just care about DH. The rest be damned.
