#3) It's a draw
How exactly do you end this rivalry when both teams are so deserving of coming out on top? Well, maybe you don't. One possible - if unlikely - outcome is that the match ends in a draw meaning that The New Day retain the belts.
You could have a hellacious match (pun very much intended) that sees all the WWE superstars laid out and unable to continue. With the Smackdown Live Tag team division lacking serious competition, this is a good way to prolong the feud as well.
