I say Oakland
They will struggle with a new DC, new HC, and trying out a new defensive formation. Arguably their best defensive player last year will be out 4 games for substance policy violation and probably in jail or released from the team for beating the shit out of his gf, wife, baby mama, whatever after he serves his 4 games. Honey Badger is a total wild card. The running game has been nothing special, we will see what an injury prone Mendenhall and Williams can accomplish. The O-line improved, but you add a rookie into the mix and it could revert them into the worst O-Line in the NFL as they started the first half of last year. Palmer is past his prime and has one target in Fitzgerald.
