Undefeated:
Bengals
Eagles
Cardinals
Winless:
Jaguars
Raiders
Buccaneers
Bengals are coming up on a gauntlet after their bye week. @NE, CAR, @IND, BAL. I don't think they'll make it through that unscathed.
Eagles travel to SF next week so that'll be tough but if they win, they have a few softer weeks before facing ARI in week 8.
Cardinals have a bye then go to DEN. Not expecting them to pull that off.
Bucs look fucked. Their most winnable games are MIN and @CLE, and neither are going to be easy for them. The rest of the teams on their schedule don't really have an excuse for losing to TB.
I think Jacksonville will win a game before the end of October. Oakland should win something before the end of November.
