What’s great about this team is their arc of improvement.
I would put money on the Bills in re-matches with the three teams that beat them (titans, chiefs, and cards). I think the more battle-tested they are, the more difficult of an out they will be.
you also have to consider what a weird year it’s been. We don’t really know who is elite yet. That is due to how putrid the NFC East is and most of the AFC south. So I have no idea how you evaluate the steelers, Ravens, or Browns.
