So, there are a lot of IFs in this take, but, my thinking is:
IF the Bills can get to 13-4 final record, a Ravens loss this weekend gives them their 3rd loss, with Buffalo already having played and beat them. The Ravens would need to WIN OUT (assuming Bills 13-4) to pass the Bills. The reason I think this is preferred is that Buffalo still plays KC and has an opportunity to give them their 3rd loss in a few weeks.
So, assuming the Bills can get to 13-4 (with one of the Bills wins coming against KC in Buffalo), a Ravens loss this weekend would make the Ravens have to go 13-0 the remainder of the season to pass the Bills and would make the Chiefs go 13-0 (outside of the loss to Buffalo assuming that happens) to pass Buffalo.
Again, none of his takes into account what any other AFC team does.
How was he against the Bills and Chiefs last decade?
