What happened: KC-LV narrowed the weekly debate over which teams can still make it through another slate without a loss.

Why it matters: Unbeaten watch matters early in the NFL season because each surviving perfect start sharpens the standings race and the weekly contender picture. This item does not hinge on a roster move or injury update, so its impact stays in the conversation tier rather than the transaction wire.

What to watch: The next shift comes as the rest of the week's games finish and the remaining unbeaten field changes again.
