I think the AFC is a bit more unsettled, for multiple reasons (a lot of QB turnover, injuries already impacting, trying to guess where the Browns will be when Watson is available to the Browns, major coaching and system changes still being worked through, etc... But, if I had to put an 8 down today, right at this minute, I'd probably go with 7:
Bills
Ravens
Colts
Chiefs
Dolphins
Bengals
Chargers
and pretty much just close my eyes and point to one from the next group (Patriots, Browns, Broncos, Raiders). And the Titans could still, at least theoretically, turn things around (facing Raiders, Redskins and Colts twice in the next 4 games).
