Jets probably should be favorites. They have had a great defense, Oline has been improved-not sure how much. Really all depends on Rodgers, probably just has to be average for them to win 10 games (they won 7 last year). If he is above average or better, they could win 11 maybe even 12 games.
Bills have some questions at WR and Defensive backfield. If WR room proves decent, Bills can once again win the division. Really is a tossup.
