“The bad news: The Bills might be the worst team in the NFL. (ESPN’s Football Power Index agrees.) The good news: FPI gives the Bills a league-high 37 percent chance to obtain the top pick of the 2019 NFL draft. -- Koontz”
The Chargers moved up one spot from 13th to 12th.
NFL.com keeps the Bills in last as well. Even though the score was 31-20, they say the Chargers, “tapped the breaks” in the second half, despite McDermott taking over the defensive play-calling. The Chargers moved up three spots from 14th to 11th.
Sports Illustrated’s Monday Morning Quarterback had eight of their writers this week vote on each teams ranking. Seven of those eight voted the Bills in the 32nd spot while one voter moved them all the way up to 30th. The Chargers moved up one spot in their rankings from 12th to 11th.
CBS Sports have the Bills in last place and don't see them moving out of that spot any time soon:
“It’s going to be a long season for this team. I would be shocked if they ever leave this spot.”
No explanation as to why, but maybe there isn't one needed. The Chargers stay stagnant at the 16th spot for their rankings.
Finally, SB Nation has the Bills in the last spot, the same spot they resided last week while the Chargers don't move and stay in the 13th overall slot.
